I got goosebumps watching this. It's 2019- 8 years after this talk- and I'm beyond addicted to Duolingo, learning one of the most remote languages in the world (Danish), and I'm one of many millions of people learning languages on Duolingo. This talk pre-empted the insane success Duolingo would have, alongside his other superb products. What an amazing man. There should be a book/film about his life.
"The story about a guy who chose to use human beings as slaves for profit while selling them the idea of world peace". Very similar to how Mark Zuckerberg operates btw.
People like him are the reason why I feel more proud every day of being Guatemalan. People just see bad thing about my country but the truth is that Guatemala is full of beautiful things and people. Keep the good work Luis!
Wow. I started on duolingo a week ago and it's ten times better than any paid language teacher I've had in the past... Language has always been my worst subject but I've picked Spanish up with ease.
I just happened to meet Luis in one of the podcasts I was listening to and to be honest, I hadn't heard anyone like this guy who in the Computer Science industry, looks at this kind of problems from such a perspective. Today, in 2020, Duolingo has become one of the most relevant app in the whole universe of the internet. Kudos Luis!
Orgullo guatemalteco exportado al mundo! Este chavo es un genio. Al fin recibi mi invitacion para duolingo y he aprendido mucho aleman en tan solo 1 semana! Gracias Luis por tu aporte a la humanidad, seras recordado por todos los tiempos por trabajo. QUE NIVEL!
I didn't know Duolingo was made with this purpose! Its amazing. I have been using it for almost a year and it hasn't disappointed me at all. Great job guys!
THIS WEBSITE HAS CHANGED MY LIFE! I am too poor to afford classes or anything to learn.. But now im being recognized by job opportunities because I know another language.. THANK YOU DUOLINGO
Go to Wikipedia, enter a search term or phrase such as "Duolingo" and look at all of the language options on the left side of the screen (on Desktop version) or click the middle icon at the bottom of the screen in the Wikipedia app on your phone.
+Natália de Jesus Actually, this has changed my whole perspective on Captchas and reCaptchas. I have been using Duolingo for a couple of years but had no idea about this backstory. If you understand spoken Spanish, you should hear his presentation on the same subject. Awe inspiring.
mind officially is blown. This is just incredible. I love this approach. I really want to start using Duolingo soon now, but I have a long way to go in the language I am currently learning, Icelandic, which is not offered on Duolingo....
This is the best and most addictive language learning program in the world. Thank you Luis. You are obviously one of the smartest people in the world. Best wishes for continued success.
I came very close to paying for one of the commercially available conventional language courses - It could have cost me close to £500.00. Then I chanced upon Duolingo. My motivation to learn a new language has been now been fuelled by the fact that I make a positive contribution to the collective learning for the whole planet every time I undertake a brief daily language lesson. Awesome!
This is incredible! I'm using Duolingo right now for Hebrew and Spanish, but I had no clue that the later stages of the site will do such great work as translating the Web! That's truly exciting!
mi angel investigador no, aprendí inglés por medio de una mezcla entre primariamente clases tradicionales pero también lo mejoré al vivir un tiempo en EEUU
+Federico Olivares is better to stick to one language and get to a decent level, then move on to another language if you want, I always at idiots on duolingi forum with 10 languages on their learning goals lmao
Latin Lover my Japanese is mid level, as long as you are not learning 10 languages from scratch at the same time, 1 or 2 plus one you are already mid level at
duolingo is an extremely great learning tool! i started learning french a month ago and now i am level 10 and i had made enormous improvement for my french!
I love duolingo. It helped me get a jump start on learning Dutch and then I was able to go from there and find other sources but it's fun and motivating to go the their website daily to learn a little bit more.
I think Duolingo will be a great tool to educate people around the globe... education brings progress to nations, never take education for granted my friends.
I've been doing Duolingo for ages and have been finding it really effective, but had always wondered how it was viable for them to make it free. I would never have imagined the explaination would be as awesome as this. What a fantastic idea!
I've been using Duolimho since April 2013 and I'm a witness to the amazing capabilities it bestowes upon the human brain. I chose to learn French and can now read and make coherent sentences! I never had a French class my life and once I become fluent in French I hope to learn Spanish, Japanese, and other languages!
+Fabienne Kapteijns Lol, I think the sentences in the actual tree are still made-up sentences, as it were. The translation aspect is a separate part of the site, at least nowadays. ... Right?
You did a wonderful job explaining yourself in english. :) And I totally understand your point. Those people I saw in Brazil who go out each day to farm or do other hard manual work to support their families are heroes to me. Someone needs to do the farming, but my hope would be that they could also learn new skills and have good access to schooling for their kids! But this is a great start, right? Poorer people who can afford some internet access but not language classes can learn! :)
I've been using DuoLingo for years and I have loved it. Now that I realize that DuoLingo is super-productive-capitalism, I love it even more. Well done!
Been on Duolingo for about three months. Amazing system that offers about a half dozen languages, all free. At the rate I'm going should take about a year to complete, which is equivalent to third year university French (my subject). Lessons consist of short spoken or written phrases of increasing complexity which should be translated. Each phrase has a comments section where users post questions usually about grammar and receive answers from other students. Totally free of cost or advertising.
I love Duolingo. I have been learning French in school for about seven months now; and in the two weeks I have used Duolingo I have learned more French than I have in all seven months of school.
You can criticize whatever you want, ainen Apfel, slave labor...... Than you really miss the essence of the story! This is innovative, i think everyone who criticize is jealous that he or she didn't come up with the same idea! This is inspiring, even if it seems to be that duolingo is a fail in a few years, its about thinking different!
Yeah, I guess you are right. This doesn´t solve all our problems, but it may be a good way to help those who have access to internet. Al the end there´s no way this is a bad thing. Thanks for your point of view and saludos desde Guatemala.
I found the CAPTCHA part of this really interesting. While I was watching this I thought to myself "he should make a website designed for just CAPTCHAs." (that is if there isn't one already) What I mean by this is, a website that you can go to just to fill out CAPTCHAs, which would be for people who are interested in helping to digitize books, because I am now interested in helping with this, but I don't want to go signing up for a bunch of random websites just for the purpose of filling out CAPTCHAs. So if there was a website that had nothing but CAPTCHAs to fill out, that would be cool and helpful
It seems like Duolingo's idea changed slightly, because the sentence translations and the language learning are two separate parts of the site. I know that because Duo uses sentences that make no sense like "Der grüne Bär ist unsichtbar"
No, you've got it mixed up a bit. There used to be a translation feature which would allow users to very quickly translate specific articles, however the actual learning part of the tree is what he is talking about here which translates individual sentences
@starkiller1 He does not say that charging people for something is unfair. What he meant by "unfair" is that at the moment, rich people have easier access to education (i.e. learning a language). In fact, in his project, people are also charged, but you pay with your time (and work), not with money.
This might work as a way to "read" a language, although I am highly skeptical about that as well. Language is much more than just a collection of words. To claim that you can "learn" a language this way is at best illusory. What about listening, speaking and orally understanding the language?
This guy is a genius! The best language learning app on the market, for free, and still making profit in such an elegant way! Awesome!
Take a look around now. See how everything has changed?
@@WXYWork what do you mean? changed in a good or in a bad way?
He's brilliant. Recaptchas and Duolingo are two outstanding ideas!
Yes, he is.

I see positive energy
I always wondered how the makers of duolingo can afford to make thier language learining programs free, and now I know. Awesome!
Duolingo is awesome, everybody should use it.
No wonder Duolingo's logo was an owl. Severin Hacker, the presenter's graduate student whom he spoke of, was wearing (guess what) an OWL mask!
Or maybe because owls represent wisdom.
I am going to go with my version, LOL. Seems more logical.
P90Jungle yes! your version seems more accurate
Oda Skjørestad Haha :)
Wow. I started on duolingo a week ago and it's ten times better than any paid language teacher I've had in the past... Language has always been my worst subject but I've picked Spanish up with ease.
OMG i just realized how this app works! excellent! thanks for making this free... this is so great!
I am learning Spanish on Duolingo right now, and it is the coolest app ever. Thank you for pushing humanity to learn about their own history.
if I ever get an owl, I'm calling it duo! God bless you, duo!

This genuinely makes me happy!
Crazy that this talk only has about 360 mio views. One of the all time best Ted talks!
I do not say that very often BUT this is such an intelligent guy.
Thank YOU so much for your effort,i enjoy duolingo so much and its even addictive.
Came here after listening «How I Built This» w/ Guy Raz, loved it!

And here we are 12 years later and Duolingo had a Super Bowl ad paired with the notifications that it sends, really a marketing and futuristic genius
He's so funny, and brilliant. :o
He will be a very important inventor later on in history
Felicidades sr Luis von Ahn, un Orgullo para Latino America, siga creciendo y dandonos productos con tanta utlidad para la Humanidad...
I've been using Duolingo for a really long time but I knew none of these things until today. Thank you Luis von Ahn!
Duolingo is the only thing more awesome than Luis voh Ahn himself! This is a GREAT TED talk, one that made me feel smarter the whole way through.
This is incredible! I'm using Duolingo right now for Hebrew and Spanish, but I had no clue that the later stages of the site will do such great work as translating the Web! That's truly exciting!
i speak spanish and english fluently to a native level, im learning japanese, and i started german on duolinguo today!

Did you learn Japanese at duolingo? I don't think that would work too well as it's very rule based.
Duolingo is a great tool for practicing my language skills
The whole world should work this way.
The Duolingo Spanish podcast brought me here! Bravo! What an incredible use of human efforts! ❤
duolingo is an extremely great learning tool!
i started learning french a month ago and now i am level 10 and i had made enormous improvement for my french!
I am German and learn Polish at the moment. Duolingo is the most natural way I could think of. I learned more in 47 days than I did the last 2 years.
That is amazingly inspirational and mind blowing
I am learning German in duolingo, thank you very much Luis!
Doulingo went from optimistic future for internet to that-place-were-the-creepy-green-owl-lives-and-blackmails-you-into-learning-Klingon.
I love duolingo. It helped me get a jump start on learning Dutch and then I was able to go from there and find other sources but it's fun and motivating to go the their website daily to learn a little bit more.
And look at the etraordinary growth of this application since last 12 years. I, myself have been using duo for over 2 years now.

Duolingo hsa been a really good experience for me. They've made French and Spanish CEFR certified, so that really puts value to Duolingo.
This is the most interesting video I've seen in a while. Really amazing.
¿Por que no hay más personas así en este mundo?
Soy usuario activo de Duolingo y apenas me vengo enterando de esto, es realmente increíble

Wow! Easy to see why von Ahn is a MacArthur Genius Grant awardee. His works are world changers.
THIS EXPLAINS WHY I KEEP SUCCEEDING ON THE WORDS I CAN'T READ!

damn i had no idea that i was translating the web by learning german, this honestly makes me want to do duolingo more! Danke und guten tag!
It's five years later, and I am using Duolingo in conjunction with a Spanish course. It's the first time I've had any success learning a language.
SAME HERE !
Honestly, it is very useful for me I can learn a lot from it. I like it very much.
I love Duolingo. I have been learning French in school for about seven months now; and in the two weeks I have used Duolingo I have learned more French than I have in all seven months of school.
Like damn, after 13 years, it is the most popular app of learning languages globally. That's crazy!
I finally got into Duolingo too, and it's absolutely amazing. I can't wait for them to add more languages, like French and Hebrew
