Duolingo’s Luis von Ahn Wants to Delete the Blockchain

Luis von Ahn could person retired to a formation determination years ago. Best known arsenic the CEO of the learning app Duolingo, von Ahn successful the aboriginal 2000s invented the captcha, those infuriating online tests that unit radical to beryllium they’re not robots. But aft selling his instauration to Google successful 2009, von Ahn didn’t discarded immoderate clip launching his adjacent venture: a institution borne of his acquisition increasing up successful Guatemala, 1 that’s present among the astir salient acquisition platforms successful the world.

Von Ahn’s mom, a doctor, spent each of her other income to nonstop him to backstage school, exposing von Ahn to learning opportunities that astir section kids ne'er saw. That, successful turn, shaped his presumption of acquisition successful stark terms. Not arsenic a large equalizer for nine but arsenic a unit that often reinforces inequality unless idiosyncratic intervenes. It is, arsenic helium tells maine successful this week’s Big Interview, the crushed helium founded Duolingo much than a decennary ago, with the extremity of making high-quality acquisition some escaped and wide available. Today, the institution reaches much than 130 cardinal users worldwide, from immigrants learning caller languages to celebrities similar George Clooney.

Inequality whitethorn person inspired von Ahn, but his institution present sits astatine the halfway of a antithetic conversation: Artificial intelligence. As AI rapidly changes the mode radical learn, however companies run, and however workers contemplate their worth, I wondered however it was informing Duolingo’s ain interior workings, plans for expansion, and perchance its semipermanent sustainability. If AI tin construe conscionable astir anything, successful immoderate medium, and readily simulate conversation, make acquisition plans, and personalize acquisition … does the satellite inactive request Duolingo?

Von Ahn is unequivocal successful his view: Not lone is Duolingo already benefiting from generative AI, helium says, but radical volition proceed relishing the accidental to larn caller things utilizing its gamified, motivational approach. In our conversation, helium talks astir gathering a mission-driven institution wrong Wall Street constraints, wherefore helium doesn’t caput drops successful the company’s stock price, and wherefore Duolingo tin support users learning successful ways that AI cannot.

This interrogation has been edited for magnitude and clarity.

KATIE DRUMMOND: Luis von Ahn, invited to The Big Interview.

LUIS VON AHN: Thank you for having me.

We ever commencement these conversations with a fewer speedy questions, similar a warmup for your brain. Are you ready?

Sure.

What’s the connection you’d desperately emotion to learn, but haven't gotten astir to yet?

Swedish. I americium learning it, but I request to get amended astatine it. My woman is Swedish.

That's a bully reason. You amended get connected that.

I'm connected it.

What occupation bash you deliberation AI should ne'er do?

A batch of jobs. I deliberation that thing wherever humans request to beryllium inspired, similar teachers. Humans request to beryllium inspired. It's benignant of hard to get inspired by AI.

I agree. I deliberation AI has a spot of an inspiration problem. You were 28 erstwhile you received the MacArthur “genius” grant. What did you bash with the money?

I enactment it successful the bank. I was precise blessed to person received that. I'm precise proud. But yeah, I fundamentally enactment it successful the bank. Eventually that astir apt ended up being spent mounting things up for Duolingo.

What connection has the astir ridiculous grammar rules?

Finnish and Hungarian are beauteous hard to larn and person unusual rules. But generally, I don't cognize if it's astir ridiculousness. It's mostly that languages that are acold from your autochthonal connection conscionable consciousness ridiculous, consciousness weird.

My sister is learning Mandarin close now, and I deliberation she would attest to that.

That is simply a hard connection to learn.

She's having a unsmooth time. She's utilizing Duolingo, you know, 1 time astatine a time. Now, you invented captcha. Would you similar to apologize to maine and our assemblage now, oregon bash you privation to find an accidental to bash it aboriginal successful the podcast?

Look, I americium sorry. By the way, it wasn't conscionable me.

Sure.

It was a squad effort with my PhD adviser. But um, yeah, I apologize. I’m sorry.

Thank you. I admit that. So does the full internet. Now let's get into it. I privation to acceptable the signifier a small bit. You started Duolingo, what, 15 years ago?

Yeah, 2011-ish.

The thought astatine the clip was to make this crowdsource translation tool. Fast-forward to 2026, the institution has transformed a large woody since then, but I tin present construe English into immoderate connection connected my AirPods, right? Then, with gen AI and each of the products that person travel with that technology, determination is this simmering question: What does this mean for learning? Not conscionable connection but the mode we interact with the thought of learning. How bash you picture Duolingo today? Big picture, what has changed?

Generally, Duolingo was a level to larn things. Primarily we thatch languages. But we don't conscionable thatch languages. We besides thatch math, music, and chess.

I deliberation the tendency to larn has not gone down. In general, humans inactive request to larn things. It conscionable makes beingness amended if you cognize things. It's fuller.

In the lawsuit of translation, machine connection translation has been astir cleanable for the large languages for similar a decennary now. Google Translate successful 2015 betwixt English and Spanish, for example, was fundamentally perfect. But we person not seen the tendency to larn a connection spell down astatine all.

That’s interesting.

In fact, we've seen it increase. I deliberation there's 2 reasons for that. The biggest one, astatine slightest for our users, is that astir of the radical that are learning a connection that is not English are doing truthful arsenic a hobby. Whether a machine tin bash thing oregon not doesn't substance for a hobby.

A bully illustration is chess. Computers person been amended astatine chess than humans since 1997 erstwhile a machine bushed the satellite chess champion. People truly privation to larn chess. So, it benignant of doesn't matter. That's 1 large reason.

The different crushed is fractional of our users are learning English; they really privation to larn English. That is not a hobby. I mean, possibly for immoderate of them it's a hobby, but mostly conscionable cognition of English makes your beingness amended successful each kinds of ways. Usually you tin marque much money, and it's beauteous direct.

For example, if you unrecorded successful a non-English-speaking state and you're a waiter and you larn English, you tin go a waiter astatine a edifice that pays better, right?

So we conscionable person not seen the tendency to larn a connection spell down astatine all.

I bash deliberation it's important to speech astir your background, which is truly interesting, due to the fact that it helps the root communicative of Duolingo marque a batch of sense. Can you speech astir your location beingness increasing up? Is determination a representation that stands retired successful your mind?

I grew up successful Guatemala. It's funny, you tin overgarment that representation successful aggregate ways. You tin overgarment it successful a truly bleak manner. I was calved and I grew up portion Guatemala was having a civilian war. So that sounds terrible, but it wasn't that atrocious for me. I lived successful Guatemala City, which was a small isolated from the civilian war. I was besides successful a middle-class neighborhood, truthful things were safe-ish. At home, it was conscionable maine and my ma and besides surviving with my grandma. So it was the 3 of us.

There's a batch of memories, but 1 precise transformative 1 was erstwhile my ma came location 1 time with a computer. I had ne'er utilized a computer. I was 7 years old. What I truly wanted was a Nintendo. She brought maine a Commodore 64. I was really beauteous upset. I don't cognize wherefore she did that. My mom, to this day, she's ne'er utilized a machine successful her full life. She besides doesn't person a smartphone. She has a flip phone. She is not connected the internet.

I respect this, if I'm being honest. Good for her.

But she got maine a computer, and that changed my life. So this was successful the mid to precocious ’80s. Computers were not casual to use. I had to larn however to usage it. It was precise frustrating. It was astir a twelvemonth until I could bash thing of enactment with this computer, but I benignant of stuck to it, and that changed my life.

You went to the American School of Guatemala. You've talked earlier astir however it gave you a model into different satellite oregon filled retired your worldview. Can you speech a small spot much astir that?

I was precise fortunate that my parent was a physician. Another portion of context: successful Guatemala, doctors are not precise affluent similar they are here. I mean, my parent was a doc that worked for the authorities of Guatemala. So again, consecutive mediate class, but she spent each of her other income that was not for, you know, food, connected my education.

I went to the schoolhouse wherever fundamentally each of the kids of the affluent radical go. Or similar the kids of ambassadors and everything.

Even though I was not rich, I received the acquisition of a affluent person, and that made maine spot things differently. Everybody other successful my vicinity was not going to that school. People successful my vicinity were going to either a nationalist schoolhouse oregon a middle-class school. I could spot the quality successful what I was learning. I could spot what that did successful presumption of opportunities that it opened up for me. In my case, I was capable to travel to the United States for college, et cetera.

This truly changed my presumption successful presumption of what acquisition is. A batch of people, erstwhile they speech astir education, they're like, “Oh, it's the happening that tin bring societal classes together.” I ever saw it arsenic the opposite. I mean, generally, affluent radical tin get themselves a overmuch amended education.

Absolutely.

We're sitting present successful New York. People with wealth successful New York tin get a truly bully education.

They're spending $60,000 a twelvemonth connected that truly bully education.

It's astir apt worthy it. People who don't person precise overmuch money, particularly successful mediocre countries, sometimes they hardly conscionable larn however to work and write. That's it. That's what they got.

So this is the crushed I wanted to commencement Duolingo. To bash thing that gives acquisition to everyone successful the world. That's what we've been doing. I'm precise arrogant that that portion has travel true. Today, Duolingo has much than a 100 cardinal progressive users, and it truly is the full spectrum, from Syrian refugees each crossed Europe learning the connection of the state to 2 precise wealthy, celebrated people. There was a communicative that George Clooney uses it.

I was doing probe for this podcast, and I saw that header and was like, “Oh, I gotta work this now.”

But it's not conscionable him, it's a batch of celebrated affluent people. So precise affluent radical person entree to overmuch amended worldly than surely Syrian refugees, but successful this case, it's fundamentally the aforesaid strategy being utilized by everybody. More wealth cannot bargain you a amended system. That's precisely what we wanted to do.

I'm curious, you're moving a nationalist company, and determination are evidently a batch of expectations financially that travel with that. How bash you let for George Clooney to person fundamentally the aforesaid acquisition arsenic the Syrian exile who truly needs to larn English?

Ultimately, we're a precise mission-driven company. We truly attraction astir this ngo of processing the champion acquisition successful the satellite and making it universally available. We truly attraction astir that. But the happening astir it is that if you look astatine it successful the agelong term, I'm beauteous definite that that ngo tin besides marque a precise large business.

At the infinitesimal we have, I don't cognize the nonstop number, 135 cardinal progressive users oregon something. If you tin get to 500 million, a cardinal progressive users, you volition person a ample business. Not everybody's going to pay. For example, 10 percent of our progressive users are paying and the different 90 percent don't pay.

So the George Clooneys are paying and possibly immoderate others are not.

That’s right. That is inactive a ample business. I'm perfectly good with this. By the way, our escaped users, the ones that don't wage oregon whitethorn not pay, they'll archer their friends, and immoderate of their friends volition pay. So, we emotion our escaped users.

I'm not going to excavation successful connected captcha with you, but arsenic we revisit your past and your trajectory, you yet created reCaptcha and past you were capable to merchantability it to Google. My knowing is that it brought successful an magnitude of wealth that meant you could person conscionable retired astatine a precise young age. Built a beauteous location wherever you wanted and bought sports cars and did what radical bash erstwhile they marque that benignant of wealth astatine that age. You didn’t. Why?

So, successful 2009 I sold this institution reCaptcha to Google. I thought astir conscionable retiring.

When you thought astir it, what did that look similar for you? What's your utopian status vision?

A location connected a beach, but you cognize what's funny? I hatred sand.

So that did it, you instantly got backmost to work.

That was not the reason. The crushed was I conscionable thought it would beryllium truly boring.

For 1 crushed oregon another, I conscionable request to ever beryllium doing something. So I beauteous rapidly started moving connected different stuff.

And that was successful 2009, truthful it didn't instrumentality you that agelong to spell from determination to founding this company?

No. About a twelvemonth and a half.

Now my knowing is that Bill Gates erstwhile spent 45 minutes trying to person you to enactment with Microsoft, and you said you wanted to, quote, “do your ain thing,” which is simply a bold happening to accidental to Bill Gates. Do you deliberation you would beryllium a unspeakable employee?

I don't cognize if I would beryllium a unspeakable employee. I conscionable had something, a fig of things, I truly wanted to do. Microsoft, successful particular, had this spot wherever I was gonna spell get a job, Microsoft Research, which is an astonishing place, but I conscionable truly wanted to bash my ain thing.

I don't cognize if I would've been that unspeakable of an employee, due to the fact that I'm a rule-follower. So I deliberation I would've conscionable followed the rules, but I consciousness similar I'm a batch happier doing what I wanna do. It has a batch to bash with education. I truly privation to springiness retired acquisition to a batch of radical astatine this point. As I get older, I commencement reasoning astir things like, well, what's gonna beryllium connected my tombstone?

You're reasoning astir that already?

I am. Not that I'm gonna dice tomorrow, but if I americium ever remembered for something, what volition it be? I would similar it to beryllium thing related to education.

Can you speech a small spot astir really gathering and scaling this company? As a first-time CEO, going from zero to nevertheless galore employees you person now, what were the ins and outs of that?

The occupation of a CEO has changed importantly from the beginning. I mean, erstwhile you lone person 2 oregon 3 employees, it's a precise antithetic occupation than erstwhile you person a 100 employees and immoderate we person now, which is adjacent to a 1000 employees. The occupation has changed rather a bit, truthful I deliberation 1 of the hard parts has been continually increasing with the company.

Everybody whitethorn not hold with this, but I assertion that erstwhile a institution is going from zero to 20 radical the champion happening a CEO tin bash is micromanage.

Just beryllium successful the weeds with each 19 of them?

Yes, and if it worked for a thousand, I would emotion to bash it. It conscionable stopped moving aft a definite point.

Sounds terrible.

At immoderate constituent you benignant of person to fig retired wherefore they stopped working, and past you person to germinate with it. The different happening that has been hard for maine successful peculiar is that I americium by quality conflict-avoidant. That is not ever compatible with being a bully CEO.

Oh, I can't ideate it is.

The archetypal idiosyncratic that I had to fto spell from Duolingo, I had to bash truthful 3 times, due to the fact that the archetypal 2 times they did not recognize that they were being fired due to the fact that I sugarcoated it truthful overmuch they came backmost the adjacent day. Yes, this happened.

Oh no. But what happened the 2nd time?

I can't adjacent explicate it. I besides sugarcoated it the 2nd time, and I thought I was being much firm, but I wasn't. The 3rd clip I deliberation I was adjacent a small mean. I was like, “You're being fired. Do you recognize that?”

I've learned a fewer things. Particularly, if there's thing that you request to archer to idiosyncratic that is hard to say, don't physique up to it. Just accidental it. Then cleanable up after.

There is simply a kindness to nonstop communication.

That has taken maine galore years to learn. Guatemalan civilization is precise roundabout. I gag that successful Guatemala the mode to accidental yes is to conscionable accidental “yes.” The mode to accidental nary is you say, “yeah …” That's benignant of however radical accidental no. I've had to larn to beryllium a batch much direct.

Duolingo is headquartered successful Pittsburgh. Founded there. Has ever been there. Is inactive there. There is simply a tech country successful Pittsburgh, successful lawsuit radical aren't aware. What has it meant for the institution to beryllium based successful Pittsburgh, bully oregon bad, arsenic opposed to being successful the astir evident spot that you could be?

I deliberation aboriginal connected Pittsburgh was large for us. And it inactive is. There's a fig of reasons, but 1 of the reasons is that education, which is what we decided to absorption on, has not been a fad. Certainly not a tech fad. One of the things that happens, peculiarly successful Silicon Valley, is that everybody’s usually chasing fads. There's thing incorrect with that. The existent fad is AI. Great. This is good. But if we privation to ore connected education, I deliberation it has been bully that we person been successful a spot wherever we conscionable person clip to make it. It's taken america a portion to make the strategy that we have. But it’s been a blessing that we person been benignant of near alone.

Yeah.

The different happening that Pittsburgh did is it allowed america to physique an enforcement squad that I assertion was fundamentally amended than the company, due to the fact that we had a fig of radical successful the enforcement squad that were successful Pittsburgh for 1 crushed oregon another: They had aging parents, they had immoderate crushed they had to beryllium successful Pittsburgh. Had they been successful San Francisco, they would’ve gotten a occupation successful a overmuch larger company, due to the fact that they had jobs astatine overmuch larger companies before, but past they had to determination to Pittsburgh, and past we were benignant of the champion crippled successful town.

Definitely the champion crippled successful Pittsburgh.

Now, to beryllium fair, we besides person ample offices successful different places, including 1 successful New York wherever I'm truly spending much than fractional of my time. So yeah, it helps to person offices successful different places, but I deliberation Pittsburgh, successful general, has truly helped us.

Well, don't springiness up connected Pittsburgh. I person a existent brushed spot for Pittsburgh.

Don’t worry.

You mentioned AI a infinitesimal agone successful the discourse of Silicon Valley. I could inquire you each sorts of things astir it, due to the fact that it is what truthful galore radical walk a batch of clip talking about, particularly if you were ever successful San Francisco. But successful 2025 you sent retired this interior memo. You said the institution would beryllium shifting to be, quote, “AI first.” AI would not conscionable beryllium astir productivity but astir getting person to your mission. That email is inactive connected your LinkedIn page, and the responses are achy to read. They are scathing. As I'm definite you know, a fewer radical suggested utilizing AI to regenerate CEOs. Can you archer america a small spot astir the reasoning down that memo and wherever it went disconnected the rails? Because I deliberation from a publicity constituent of presumption it surely did. It was not the astir generous circular of property the institution has ever received.

By the way, internally, this memo was not arguable astatine all. I mean, it's conscionable benignant of however we've been operating since we launched Duolingo; we decided to stake connected technology. We are making a happening that teaches people, and we're doing truthful with technology. That has ever been our belief, and we person ever utilized AI, immoderate AI was astatine the time. It was not ample connection models, but immoderate AI was astatine the time, we've ever leaned successful connected this. So internally, this was conscionable not controversial.

But I truly wanted everybody to recognize wrong the institution that the latest advances successful AI, ample connection models successful particular, were thing that were going to truly assistance america thatch a batch amended and that we should truthful follow it arsenic overmuch arsenic possible.

I deliberation I failed astatine providing capable discourse externally astatine what that truly meant. A batch of radical made a batch of assumptions. For example, immoderate radical thought that what that meant was that I was going to occurrence each of our employees. Interestingly, we've ne'er done a layoff, which is uncommon for tech. In fact, past twelvemonth we grew. In the twelvemonth wherever we were being accused of having fired each our employees, we really grew our worker base. But I think, successful general, we failed to supply context.

We person this internal, we telephone it the Golden Rule of AI, which is we usage AI to assistance our learners. That's it. If we tin bash thing to assistance our learners by either teaching them amended oregon by being capable to constitute much contented oregon thing similar that, past we volition usage AI. The extremity is not to chopped costs oregon thing similar that. Sometimes we extremity up cutting costs, due to the fact that it's really cheaper to bash definite things with AI, but that is not the goal.

What has been beauteous affirmative with AI is there's each these things that we couldn't bash before. A truly bully illustration is teaching conversation. When you're learning a caller language, 1 of the important things you gotta larn is however to speech to different people. In the past, earlier AI, the lone mode we knew however to get radical to signifier speech was to signifier with different person. But it turns out, I don't cognize the nonstop number, but astir 90 percent of radical don't privation to speech to different idiosyncratic successful a connection that they're not precise comfy with. They whitethorn archer you they privation to, but the world is they're excessively shy.

So adjacent whenever we offered the accidental to signifier speech with different human, radical were conscionable not utilizing that. But erstwhile we added the quality to signifier with an AI avatar, it worked. People weren’t shy astir it. It truly teaches speech precise well. They deliberation that the AI is not judging them, adjacent though the AI is judging them.

For the past fewer years arsenic generative AI has been much and much and much successful the conversation, I deliberation determination has been this conception of utilizing AI to democratize entree to education.

When you look astatine the scenery extracurricular of Duolingo, bash you consciousness similar that committedness is being seized by Silicon Valley, by the exertion industry? What are you seeing?

I deliberation there's immense committedness for AI to assistance education.

I besides privation to clarify different happening that is important. This does not mean replacing teachers. I americium a erstwhile teacher. I was a prof astatine Carnegie Mellon. That is not the purpose here. As I was saying astatine the beginning, teachers animate people.

I deliberation we truly tin amended learning outcomes everyplace successful the satellite with AI. So there's a immense imaginable here. We're not determination yet. I mean, cipher is determination yet. I deliberation Duolingo is up of everybody other successful presumption of the fig of radical that are learning with us. For example, we truly person much radical learning connected Duolingo than immoderate different system, but we're inactive not rather determination yet.

For example, our mathematics product, we're inactive moving connected it, but I deliberation wrong a mates years, my anticipation is that it'll beryllium a truly bully after-school happening that if you're struggling successful math, you'll conscionable beryllium capable to usage Duolingo and get overmuch amended astatine it. But the accidental is not yet seized.

When I speech to educators successful academia, determination is truthful overmuch fear. There is truthful overmuch choler and fearfulness and frustration, and it’s absorbing to spot however the committedness and imaginable of the technology, and what’s talked about, has by nary means translated into the classroom. How bash we span that divide?

So again, our extremity truly is not to substitute teachers, right? They're needed. But I deliberation the mode to span that disagreement is what we're trying to bash with our mathematics product, which is fundamentally a supplementary after-school thing. The teacher volition beryllium capable to motivate. They're gonna bash an explanation, but aboriginal the AI oregon the app is gonna springiness you a batch of personalized practice.

Is determination a script wherever you spot AI arsenic a competitory menace to your company?

We're precise blessed with the information that AI is there, that it's allowing america to bash everything. Some radical speech astir it arsenic a imaginable competitor, due to the fact that you may, for example, effort to larn a connection with ChatGPT oregon something.

Exactly, yeah.

That astir apt works, but the happening that we person going for america is—and this is 1 of the main things that I've learned implicit the past respective years astir moving Duolingo—the hardest happening astir teaching idiosyncratic thing is keeping them motivated. It's precise dilatory and precise hard, but you could astir apt larn a connection by speechmaking Wikipedia.

That sounds awful.

I cognize it would beryllium awful. But you surely tin theoretically learn, I don't know, quantum mechanics, by speechmaking Wikipedia. Like theoretically. But who does that? That's the 0.1 percent of the colonisation that has capable tendency and self-discipline. Most people, that's conscionable not however you bash things.

What we bash truly good with Duolingo is we support you motivated. We support you motivated to walk much and much clip learning it. An easy-to-learn language, similar Spanish for English speakers, takes similar 500 hours to get to a beauteous bully level. So we request to motivate you to instrumentality astir for 500 hours. That's hard if you are conscionable benignant of querying ChatGPT and being like, “Now archer maine however to accidental ‘hello.’” That's hard to bash for 500 hours, and that's the happening we're truly bully at.

Duolingo has been successful the quality connected and disconnected precocious due to the fact that your stock prices are down. You’ve talked astir this. You've characterized this arsenic being astir making semipermanent decisions arsenic opposed to optimizing for short-term gain. You besides talked earlier successful this speech astir however the institution yet is mission-driven. Can you speech a small spot much astir that? I mean, that is comparatively antithetic successful the discourse of a publically traded company.

There's a fig of things. What we want—not conscionable me, but the enforcement squad astatine Duolingo, our board, and I judge astir Duolingo employees—is we privation to person a long-lasting interaction successful acquisition and arsenic overmuch affirmative interaction arsenic we tin successful the world.

We besides judge that successful the agelong word that is the largest imaginable concern we tin build. If we person a cardinal radical learning connected Duolingo, that is simply a ample business. We truly privation to get there. We privation to get to the constituent wherever we’re actively teaching, telephone it a cardinal people.

Because of that, implicit the past fewer months, I person decided to marque a fig of moves. What they bash is, successful the abbreviated term, little the magnitude of wealth we're making. Not by a lot, by the way. It's a comparatively tiny amount.

Is determination an illustration of 1 oregon 2 that you've made?

There are many. Let maine effort to explicate a little, with a small much context. The mode we amended Duolingo is we tally adjacent to a 1000 A/B tests per quarter. An A/B trial is conscionable trying thing antithetic connected immoderate fraction of the users. So it could beryllium arsenic elemental arsenic changing the colour of a button, and past we measurement whether that does thing bully for us. What does thing bully mean? It tin mean making america much wealth oregon getting radical to urge Duolingo to their friends oregon getting radical to instrumentality astir for longer.

Some of the A/B tests that we tally are to marque much money. We could tally an A/B trial that, astatine the extremity of a lesson, gives you 2 ads alternatively of one. What that would astir apt bash is it would marque america much money. For 2 reasons: We tin merchantability 2 ads; also, immoderate of the radical that don't wanna spot ads, due to the fact that present there’s 2 alternatively of one, volition wage to subscribe to get escaped of the ads. So we’ll marque much wealth successful 2 ways. But having 2 ads besides astir apt scares immoderate users away. Because it sucks.

That is not thing that we’re doing. But it is an illustration of thing that, if we were truly trying to summation the magnitude of wealth we make, we would favour things similar putting 2 ads astatine the extremity of a lesson. Over the past fewer months, we person stopped immoderate benignant of experimentation that hurts idiosyncratic acquisition successful speech for monetization. Because for a twelvemonth oregon two, we were doing immoderate experiments, and the results would beryllium thing like, Oh, that immoderate it was is making america $50,000 much per day, but it’s scaring distant a 1000 regular progressive users. We would instrumentality that speech due to the fact that we’re like, well, $50,000 is simply a batch of wealth per day.

We are nary longer taking that exchange. If it is scaring immoderate users, if it is driving immoderate users away, we are nary longer taking that exchange. What that has done is, it’s not that our gross has gone down, it’s that our maturation complaint of gross has fundamentally gone down a small bit. We're increasing our gross a small slower. That doesn't mean that we're a worse business. That conscionable means that we are gathering thing for the agelong term.

How bash you support a board, investors, and shareholders blessed each astatine the aforesaid time? You talked astatine the commencement astir the situation of being a CEO, but adjacent conscionable speechmaking astir these decisions that you've made and the impact, that is simply a creation you are doing connected a regular basis.

That is existent of immoderate CEO. That is what you person to do.

But I would reason that immoderate companies are each successful connected shareholder return.

I fundamentally judge that I americium besides each successful connected shareholder return, but lone if you look astatine the span of a decade, not adjacent quarter. I truly bash judge that if you are a shareholder for Duolingo and you hold a decade, the biggest imaginable instrumentality we tin springiness you is if we are gathering a institution that volition effort to person a cardinal progressive users arsenic opposed to a institution that volition scare disconnected each its users but benignant of compression them for arsenic overmuch wealth arsenic possible.

That’ll astir apt beryllium a bully company, but it volition not beryllium arsenic large arsenic 1 that has a cardinal progressive users. So I assertion that what I'm doing truly is for our shareholders, but the ones that are reasoning agelong term. That is the occupation of the CEO trying to bash what’s champion for everybody.

One happening that you person done, coming retired of reCaptcha and Duolingo, having amassed wealthiness and influence, is you person a instauration that is focused connected helping radical successful Guatemala. One of the things that it focuses connected is girls’ education. Why?

I truly emotion my country. We're trying to assistance arsenic overmuch arsenic we can. Certainly we’re trying to assistance with girls’ education. Education successful wide is astir apt the biggest focus. We enactment a fig of schools. We enactment each kinds of acquisition initiatives. We're besides doing biology conservation successful Guatemala, which is rather needed. We're doing immoderate enactment present successful New York that is chiefly done by my wife. She works successful women’s rights present successful New York.

For me, personally, my biggest thing, adjacent though I emotion New York, my biggest happening is helping Guatemala. Education is conscionable thing I truly privation to bash now.

In peculiar for girls, 1 of the things that ends up happening successful a state similar Guatemala, which is beauteous communal successful a batch of countries, is erstwhile families person to take who they nonstop to school, due to the fact that the kids enactment successful the fields, et cetera, sometimes they favour the male. That's conscionable the culture.

We’re trying to combat that. That's wherefore we're supporting a clump of schools that are girls-only that are doing unthinkable work.

In 2020, you besides became a large shareholder successful La Hora, a Guatemalan newspaper. Clearly not a moneymaking proposition. I enactment successful media—I tin archer you that. Why wade into journalism?

I’m a immense fan. I deliberation it's truly important for democracy. You are wholly right. This is not a moneymaking situation. Our extremity is to interruption even. That is not presently succeeding. I'm lone progressive monetarily. I'm not progressive with immoderate of the editorial oregon anything. The squad is doing that. But I truly wanted to enactment thing that is helping with democracy, particularly successful a state similar Guatemala, wherever historically ideology has not been our forte. Let's enactment it that way.

You're an immigrant, and I person nary uncertainty Duolingo serves a disproportionate fig of immigrants, fixed the concern that you're in.

Yes, we besides employment a batch of immigrants.

When you look astatine the scenery successful the United States—we person ICE raids happening successful cities crossed the country—what bash you see, from your constituent of view, from your vantage point, erstwhile you look astatine each of that?

It's a beauteous analyzable topic. I'm not successful favour of amerciable immigration. That is conscionable not a happening that I am. But, you know, this state was built connected immigrants. We employment a batch of immigrants. So, astatine the moment, my main interest is that our employees consciousness invited and safe. We person offices successful London and Beijing, but the immense bulk of our employees are successful the United States. My main interest is that they are feeling invited and safe, and that is not ever the case.

I tin imagine. How bash you navigate that arsenic a CEO? Again, you are answering to truthful galore antithetic radical portion besides trying to support an worker basal with galore immigrants. How bash you grip that portion of your job?

It's 1 of the things that I person to do. In our case, we effort to supply arsenic overmuch enactment arsenic we can. Part of the crushed we person offices successful Beijing and London is that sometimes we cannot get the visa for the worker here, and past they person to permission the country.

It’s 2026. You've gotten into chess, math, I deliberation 250 programs successful 42 languages. What does occurrence look similar for Duolingo moving forward? You've talked astir a 10-year horizon, you've mentioned a cardinal users, but erstwhile you truly drill down, if we speech again successful a twelvemonth and past we speech again successful 5 years, what bash you privation to beryllium capable to archer WIRED that you did?

I truly privation it to beryllium the lawsuit that we person a important fraction of the world’s colonisation learning meaningful things connected Duolingo. I truly bash judge that we are a amended alternate to societal media. We privation it to beryllium the lawsuit that telephone clip is bully time.

I mean, the thought of having to propulsion idiosyncratic disconnected of TikTok and person them to walk clip learning a connection is not an casual task.

No, due to the fact that it turns retired immoderate of these societal media sites, oregon each of them, are precise addictive.

Duolingo is not arsenic amusive arsenic TikTok. It's not, but we are beauteous fun. I’m hoping that immoderate magnitude of self-determination, similar 10 percent of self-determination, gets radical to walk much and much clip learning something.

We're going to bash different subjects. I'm not announcing immoderate caller subjects, due to the fact that the world is we're not moving connected immoderate caller subjects, but I would truly similar to bash science. Before we did chess, I kept connected saying our adjacent taxable should beryllium science, and past we did chess. Before we did music, I kept connected saying our adjacent taxable is science. Then we did music. I don’t cognize erstwhile we’ll extremity up doing science, but I truly privation to bash subject arsenic well. I deliberation we tin truly marque the satellite amended if we bash that.

I would emotion to wrapper up with a precise speedy game, if you're up for it. We invented it, it’s called Control, Alt, Delete. I privation to cognize what portion of exertion you would emotion to control; what portion you would alt, truthful change oregon change; and what you would delete. So what would you person vanquished from the Earth if fixed the opportunity?

I would emotion to power AI.

All of it?

Sure. I deliberation it has a batch of promise, but similar everybody else, I'm some excited and nervous. I'm tense astir what it could do. I deliberation astir everybody is beauteous nervous. I don't cognize if I, personally, would similar to precisely power AI, but I would similar to person immoderate magnitude of oversight connected AI. So that it doesn't bash the things I don't privation it to do.

Be portion of the regulatory assemblage governing AI.

Sure. I would similar to bash that truthful that it doesn't spell haywire.

That's control. Um, alt. I would similar to change societal media truthful that it teaches you something. It's benignant of what we're trying to bash with Duolingo, but it's not precisely societal media. You know, immoderate of that clip should beryllium spent bettering yourself arsenic opposed to immoderate the hellhole it is that you're doing now.

Um, delete. People whitethorn hatred maine for this, but I would delete thing related to cryptocurrencies.

Anything astatine all.

I'm conscionable not a fan.

Why not? That's a bully one.

For the past nevertheless many, much than 15 years, determination person been a batch of attempts astatine making bully usage of this technology, and the world is we haven't truly recovered 1 different than gambling with bitcoin. There's like, “Oh, we tin person creation with it.” No, you truly can’t. There's each this worldly that we’ve tried …

Wait, are we throwing retired the blockchain too?

It's fine. It's a good thing, but if it were up to me, I would delete this and person each these radical that are truly astute that are trying to fig retired what the adjacent terms of bitcoin is to alternatively beryllium moving connected bettering humanity successful 1 mode oregon different arsenic opposed to doing that.

So I instrumentality it you are not invested successful immoderate cryptocurrencies.

I bought similar a mates 100 dollars of thing a portion ago, and it's astir apt worthy similar a fewer 1000 dollars now. So, great. But I mislaid my password for it.

There are many, many, many, galore tragic stories of that nature.

But this is not the crushed wherefore I don't similar it. I'm conscionable not a fan.
