- Following backlash to statements that Duolingo will be AI-first, threatening jobs in the process, CEO Luis von Ahn has tried to walk back his statement.
- Unfortunately, the CEO doesn’t walk back any of the key points he originally outlined, choosing instead to try, and fail to placate the maddening crowd.
- Unfortunately the PR team may soon be replaced by AI as this latest statement has done anything but instil confidence in the firm’s users.

Reminds of Proto CEOs faux pas
Good to see the normie finally turning on these cult of personality clowns imitating Steve apple..
I can't be believe we had to suffer 15 years of it.
These parasites been getting high on their own farts for too long while normie LARPed everything they said.
Not much of a “faux” pas. Not only did he double down on it, but the board supported him.
The plural of faux pas is also faux pas, because you know, French. But this is less one false step in the dance, than doing entirely the wrong dance altogether.
Oh thanks for re-teaching me that one! It’s been far too long since I last used French reallistically.
Even tho it’s better that I took that than German, otherwise I’d understand the ich_iel memes which would make them lose half their charm.“the board” lol yeah they used to be governing mechanisms instead of a clown car full of sycophants.
Now please explain in more detail how this advice should be followed, practically, by someone you just fired because AI was cheaper. Give examples of how they can “stay ahead of it” so as to “remain in control of the product and mission” they are no longer employed to work on. How should they “embrace” this transition and “respond with curiosity” to no being newly unable to afford food or rent? “Uncertainty for all of us” my ass.
The former employees are now curious about how they will pay rent and eat, so there’s that.
What is the point of this news that talk about a walk back that is doing nothing to walk back?
In 2025 everything is just a messaging problem to these goons.
I mean, it is too late. Canceled my sub, won't be coming back.
Same. Deleted the app this weekend and let my 918 day streak evaporate.
I’m actually kind of surprised at how little it affected me, to be honest. I had a little bit pre-regret about losing the streak before deleting the app, but now a couple days later that feeling certainly doesn’t exist. AND there’s that benefit of no stupid owl guilt tripping you every day.
Check out “Language Drops” and “Rosetta Stone” if you’re looking for replacements. They both have very different approaches to language learning (both from each other and from Duolingo), but their content is at the very least much better curated than Duolingo’s.
I haven’t gone out of my way to check but AFAIK neither of them is jumping on the AI-before-anything-else train.
Would you recommend one over the other and if so why?
I just tried “Language Drops” and it was… interesting. It didn’t place me at the right level, so I got a very beginner lesson when I’m closer to intermediate (but definitely not fluent). I’m not sure I liked matching the pictures- the picture for “thank you” could mean different things depending on how you interpret the person’s face and body language- and then I hit the end of the free content for the day. It didn’t get to different tenses or even whole sentences- just basic vocabulary and no verbs. Maybe it ramps up quickly?
Sometimes the icons annoy me too and I wish the app had an option to always show the icon’s label, but at least you can tap on the icon to see the label.
As a complete beginner, Drops is pretty good for learning random words and increasing vocabulary. As you advance through it you start seeing sentences too, but it doesn’t teach you how to make your own sentences, only to memorize the ones they pre-created.
Rosetta Stone doesn’t translate anything. All of the content is in the language you want to learn and it tries to introduce you to things in a natural way. For example it shows a picture of someone biting an apple and says “the man eats an apple”, then later shows other pictures related to one or multiple men, fruits and verbs, so you can get used to the differences between things just by observing those.
Thanks for the recommendations!
I have actually switched over to Mango Languages because my library gives free access to it.
But if I don’t end up liking that I’ll give these a shot.
My recommendation is Language Transfer, a freely-available system for multiple languages that, in my opinion, helps you to think in another language better than any other system I have tried.
It has only 10 languages :(
Many libraries also give out subscriptions.to Mango. That is usually a paid app and much better than doulingo
Any recommendations for japanese?
I think both of them have Japanese (I remember seeing Rosetta Stone being praised for its Japanese content 20 years ago and I hope it would only have improved since), but I haven’t gone very far in the language in either app.
Drops had an ai feature where it would show you a “fact” at the end of each session, which was often completely wrong etymology.
I canceled my sub, but sadly not out of principle on the AI thing. I just accidentally hit the button that accepts an upgrade to the family plan and it didn’t look like there was an easy way to undo it so I just killed the whole subscription.
I hear good things about Pimsleur as an alternative.
www.pimsleur.com
Interesting.
I have switched to Mango Languages because my library gives free access to it. So I’ve been trying to share that information with people. Or, at least, check your local library to see if they offer something.
That’s great advice. At least for as long as libraries still exist. 😫
Pimsleur has been making “real” language courses for 20+ years, you could get CD’s with languages back then, there should be plenty to choose from.
I used Pimsleur to get started on my L2 way back when. I am now pretty much fluent, after living immersively for a long time. The immersion, and dedication, and tutors, and language school did the heavy lifting. But Pimsleur gets big credit for helping me get started and get confidence.
It can go either way, some people like the method, others hâte it because it’s not gamified. Pro tip, get pimsleur courses from your library if you want to try them for a real trial rather than what they give you
Where is the discussion for replacing CEOs with AI? Seems like predicting market trends based off of historical data and managing corporate resources would be just the sort of thing that AI would be good at. Plus it would cost way less and not require massive bonuses nor ownership of the company.
Well, the crux of the problem is that AI is trying to approximate intelligence. That’s not useful for a CEO.
boom
Respec the AI with lots of points into Charisma and Legal Dexterity. It also needs a large amount of Gold to get started.
If you’re gonna be a shitty company and do shitty things, just STFU. I don’t know why they think they can talk their way out of it, it’s like they believe their own BS.
Because it worked since Steve Apple did the iphone. techie bootlickers larped it all up, furiously defending "their CEO" from any criticism online. It has hard to do it now with out being called for being a pathetic bootlicker, so most don't even try any more.
The parasites are now learning that the sentiment has turned, it will take sometime until their "PR" consultants catch on and come with some new "act"
Point of order; Steve Apple actually did awesome shit. Macintosh, iphone, NExT, Pixar, saved an enshittening company, etc.
sure... good for him but why does every fucking parasite now think they can fill his shoes?
and how were they able to this cosplay for this long with out being called for it?
Well, those are different questions . . .
Those rich idiots figure you just have to act a certain way, and they conveniently forget that you also need the talent to justify the act instead of just being born with a silver spoon. It´s also that silver spoon shields them from many of the consequences and being called out.
Amen!
Last year in February I uninstalled the app on a perfect, 2000-day streak when I got the first whiff of AI; I’m probably never going back
Now say it in Spanish.
Any recommended alternatives?
workbooks and videoes and a good dictionary
thousands of great tutors are on sites like iTalki too
I just started using Duolingo to learn Spanish. Can anyone recommend alternatives they have had success with that function the same way?
Anki is free. If you need gamification, then perhaps memrize is for you. I’d just go with anki though. Ankidroid is a good app to work with the anki decks.
I tried out a bunch, including Babbel, Busuu, Language Transfer, Mango, and Memrise. I didn’t like them for one reason or another. I finally landed on Lingodeer. It’s similar to Duolingo, but it is a paid app. (You can try level 1 of any language for free.)
The regular subscription price is definitely not worth it. It’s okay (not great, but not awful) when they do their sales. But I felt okay about paying human workers.
This kind of learning is a great start, but will only get you so far. If your local library has access to Kanopy, look for the Great Courses series on Spanish. I thought that was an excellent series after a little bit of Duolingo.
Use free Anki and get a free 1k or 5k high-frequency community deck from Anki website. Or get Refold 1k deck (paid) for anki.
If you find Anki too complicated and you don’t mind paying a sub (look for discount/vouchers), use lingvist (paid) or memrise (not sure how this app is now after the changes) to learn 1k words. Any app that focuses on high frequency vocab is fine I think.
Cancel subscription once you have learnt 1k words or can read comfortably a simple native book or graded books, or understand a podcast designed for learner (example InnerFrench), probably will take 1-3 months at about 10-30 words a day.
The main difference between 1k and 5k decks is that the 5k decks include very common type of words like “the”, “a”, “he”, “she”, “is”, “are”, which are so high frequency that you will acquire them by just doing anything in the language. Either type of deck is fine, it is up to you.
Try reading graded readers with audio at the same time as you are going through your deck so you are getting more context for new words you learn. You will encounter new words while reading before seeing them in the deck, which has a positive effect in remembering the word. Reading also helps serve to test how much you have improved in using the language.
Read up on some basic high frequency grammar in your target language. Depending on language you will have to also actively learn the alphabet, numbers, phonic and so on before doing any of the above.
The main idea of learning high frequency vocab is to start consuming content as soon as possible. Never forget that using(reading, listening, writing, speaking) the language is the main purpose of learning languages.
If you like gamification and keeping scores, count the books/article read, count the words learnt, count the hours spend listening don’t count coins or gems.

Classic “I’ve made a HUGE mistake” moment from yet another “thought leader” suffering from AI/layoff FOMO. 🙄
In another thread someone told me you can buy gems or something to keep your streak going.
That would’ve made me uninstall long before his comments.
I remember easily getting gems for free. Also the streak basically doesn’t matter at all. What made me uninstall is the slow pace. It felt like I was stuck on the same words and topics forever. It felt like I was not actually learning anything, which if you’ve ever started learning a language if a formal setting, is very apparent.
I’ve found it’s best for drilling and not for learning. You’ll probably learn faster by reading a textbook or listening to something like the Michel Thomas method that gets you speaking super fast. Then you can hop on Duolingo and make it stick. The secret is knowing the vocabulary beforehand to finish the lessons faster by focusing on your accuracy instead. It’s still a lot of grinding, though. 😅
The old tree system was much better, it allowed you to mix exercises from different topics. The new path system locks you into one topic until you know all the sentences by rote.
They changed that a couple years ago, right? I think that was when I quit.
Theres also basically zero server side-checking on anything. Hacked APKs let you get premium features for free :3
Got any recommendations for where to find said APKs?
Just a guess , but maybe the extra net by the bay of torrent.
Mobilism.
That’s awful! Could you please let me know where these APKs are hosted so that I may avoid them?
Mobilism.
I’m a long time user of Duolingo and you earn plenty to give yourself the occasional streak freeze if you can’t go two days without doing a lesson. It’s not really as predatory as it sounds. It’s nothing like pay to win type games.
Fuck Duolingo for the AI shit though, don’t mistake me for a Duolingo simp thinking their blameless. It’s just that the monetization is not as predatory as it sounds.
I have so many could probably keep a streak foing indefinitely without ever doing a lesson, but I’d need to log in every couple days to repurchase the streak freeze.
Ah, okay, thanks for the info! I’ve never used Duolingo so I genuinely don’t know.
I think it should be added that people who pay premium get infinite lives, everyone else gets 1 life every 6-ish hours with a maximum of 5, meaning they can answer wrong at most 5 times and fail a lesson, forcing them to do a recap practice lesson to earn a heart and then retry the lesson with only 1 heart or they’re just done for the day.
It’s kind of pay to win.
I have so many bonus points, I just get 5 new hearts. I find the lack of grammer in the free version holding me back (possibly by design, so I’ll finally pay for something). I think it’s time to leave for me too (I didn’t enjoy the gaming side and won’t tolerate AI integration, even if it’s free).
To win what? The lessons are not competitive.
There actually is a weekly leaderboard bracket where you compete with about 30 to 50 other people.
Completing a lesson is winning, losing all your lives is losing.
A completely optional, side objective that has no bearing on anything else? You can completely ignore the leader board and still progress. It’s not competitive.
Yeah of course, winning or losing a game has no bearing on anything. It’s still winning or losing.
The main objective is to complete lessons. You have to pay to do that or wait for energy to replenish.
No, you don’t. It’s only when you lose hearts. You get to make 5 mistakes. You can use gems to replenish them or they replenish over time. After playing for a while you earn plenty of gems to restore your hearts mid lesson every now and then. You can watch an ad to replenish your hearts between lessons, but not during. If you’re not making mistakes then you can keep going. It’s not that difficult to not make mistakes either, a lot of times they flat out give you the answer by tapping on words.
There are plenty of things to shit on Duolingo as a company. Calling the app pay to win really isn’t one.
The main objective is not to complete lessons, but to learn. If you use up all your hearts because you make too many mistakes you’re obviously not learning. At that point Duolingo completely fails though, instead of telling you to go back and practice, it asks if you want to buy hearts with in-game currency or switch to the paid super max hyper ultra AI whatever it’s now called for unlimited hearts. Unlimited hearts doesn’t give you shit though, it allows you to bruteforce your way through the lessons to get XP to rank up in the completely optional leaderboards, it doesn’t help you learn. It’s only pay to win if you see it as a game and not as a language learning app.
You can set your profile to private to completely disable the leaderboard stuff.
Nobody has ever learned a language by using Duolingo anyways. It’s an app that lets you pretend your are doing something useful with your life instead of just slaving away at your job enriching others.
Jesus fucking Christ, lighten up lol.
the realest comment on lemmy, ever
I have definitely learned a lot of Spanish from Duolingo, and while I’m not fluent, i went from being able to count to able to hold some basic conversations with Spanish people i know.
You’re just pretending you are doing something useful with your life instead of just slaving away at your job enriching others.
/s, obviously. What a wild take they have.
You had me to the /s, NGL
“Freezing” your streak is just silly, even if they offer it for free. Is this just for online clout, so you can brag (falsely) to others how long you haven’t broken a streak?
If an alcoholic goes 10 years without drinking, then has a beer, the streak is broken. Doesn’t mean you can’t recover and improve, but it is what it is. It’s dishonest to pretend it didn’t happen, especially if you’re comparing yourself to others…
Really comparing missing a day of a language learning app to alcoholism recovery?
Your streak doesn’t go up on days you use a freeze.
No? It was a comparison of the streak, not the subject of the streak. That was just an example. My point remains. Unless you can literally stop time, the streak died. It’s okay that it did, but why pretend it didn’t?
If you can’t see why someone might have a different criteria for a streak in days without alcohol as a recovering addict and days in usage of a learning application I can’t help you.
It’s worse than that.
Yes, you can pay for a streak freeze. If you don’t, you’ll probably find that you were given one for free anyhow. You’d have wasted your gems.
Yes, you can pay to undo a streak loss. It’s more than paying for a freeze.
It’ll give you multiple chances to pay for all that, too. If you’re out for days and then come back, you can pay to fix your streak.
What is the point of a streak if you can just buy your way back to it?
Also, I had paid for the last couple years, which (IIRC) includes free streak freezes. It still asked if I want to pay for them. I’d say no, and find I had one anyhow, or a friend had miraculously given me one.
But during the last year (365 days) my streak was actually only at 190 or so because I’d used so many streak freezes that I got for free. I wasn’t even trying to keep my streak.
When I finally let my streak die, the icon started trying to guilt trip me into coming back with horrible icons of Duo being sad, heartbroken, or even dead.
The constant mental manipulation that was well beyond what gamification should ever be was what finally drove me to just quit playing altogether. I had already canceled my sub long ago, but I’m not even going to use the remainder of this year I’ve already paid for.
The missing comma in the second bullet point changes the meaning of the sentence.
I deleted the app the second he said this. Get fucked, AI.
Make sure you also start the account deletion process.
Tl;Dr: skip the apps unless they’re part of a bigger in-person course. Prefer reputable sources like pimsleur and mango languages. If you have no rush, get graded readers and watch a lot of YouTube, podcasts, etc.
Ok, so here are my two cents on learning languages and the whole category of learning apps. They are all flawed on some major way or another. But mostly it is about pacing learning progress.
Teaching absolute beginners is easy. They know nothing, thus anything you show them will be progress. The actual difficulty when learning a language is finding appropriate material for your level of understanding, such that you understand most of it, but still find new things to learn. This is known as comprehensible input. The difficulty of most apps is that they are not capable of detecting then adapting study content accordingly to the student’s progress. So they typically go way too slow, or sometimes too fast. Leaving the student frustrated and halting learning.
Jumping with some nonzero knowledge into any app is also torture. It’s known as the valley of despair. The beginner content is too boring and dull, now that you know a bit, but the intermediate level is way too much of a gap for you yet.
My advice is to skip language learning apps. The “motivation via gamification hypothesis” is flawed and lacks nuance and understanding of behavioral science. People don’t stop studying out of a lack of tokens, gems, streaks or achievement badges. It’s because the content itself is uninteresting and bores them. Sure, the celebration and streaks work at first, but they usually lose effect by something known as reinforcement depreciation. The same stimulus shown too much or too frequently stops being gratifying. The biggest reward for learning a language is actually using it.
A method that is known to work is to find graded readers. Watch a lot of YouTube, podcasts, social media, in the target language (avoid the language learning influencers) listen to native influencers speaking about topics you care about. Books work, in-person courses work, learning apps are good to start you up form absolute zero. But most learning happens on what you do in your everyday life. Using the language is the most effective way of becoming good at the language. Everything else is just excuses for using it.
exactly. I also don’t appreciate the app changing the icon to guilt trip me back into their odd choice of/irrelevant vocabulary that I am supposed to learn
You put into words exactly how I’ve felt about language learning apps. Every time I try a game or app that’s supposed to teach you, it feels like I’m starting over, and it never actually becomes fun. I tried Duolingo, but after a while, I found myself just doing super easy lessons to keep my streak going so I wouldn’t have to sit through the boring ones. It felt pretty bad, so I stopped using it when I hit 800 days.
My friend didn’t use any apps and instead started by texting and talking with people and managed to learn Korean in just a year, well enough for casual, everyday conversations or hobby-related stuff. Meanwhile, I’ve been using apps and still can’t hold a conversation with anyone…
…or join a reputable language learning academy and go to class in person.
Though I know this is not for everyone. But neither is self-learning online.
AI is social cancer
It’s a lie told by marketing companies that have gaslit artists into automating their creativity and gaslit governments into automating fascism
Automated fascism completely defeats the purpose of fascism. The whole point is to lord power over people, if a computer is going to do it automatically then it’s no fun.
AI is social lung cancer. Behind social media, which is social bone cancer metastasized.

Just say AI bad use is cancer for human kind. Good use can help humans to do their task with less effort. So its all depend on usage.
I love this headline so, so much
I want every headline to end with “…, fails”

Bragging about replacing your employees publicly over and over before actually being able to do so might cause an employee crisis
boring, broken garbage content. monthly subscription fee. get the fuck out of here
What I’d wonder is why it’s such massive expensive for Duolingo to hire 2 or 3 people to cover a language anyway. Presumably most of the work is contractual - hire somebody competent to produce a course, get somebody to say the lines, refine the course based on feed back and that’s mostly it.
Terminal MBA brain
I would assume it is more about time than money. It is a big investment making a whole functional system with llm (I have a hard time believing it is actually AI), it will cost a lot if done wrong (just like everything else). You can’t just prompt “make a course in Spanish” and get anything good out of it and you still need ppl who can quality check the output. I could see them use it to mass produce sentences and stories in different levels (not the actual story) and voice recordings, but not actually anything creative and I would assume that is the goal. But we have seen too many shitty products to believe in anything with llm.
How do these people become CEOs they’re as thick as several short planks nailed together.
Firstly every single company that has tried to replace its employees with AI has always ended up having issues. Secondly even if that wasn’t the case, people are not going to be happy about it so it’s not something you should brag publicly about.
If you’re going to replace all of your employees with AI just do it quietly, that way if it fails it’s not a public failure, and if it succeeds (it won’t) then you talk about it.
If they do it quietly, they won’t get the stock price bump every company gets from saying they’re going to replace (costly) employees with AI.
Intelligence has nothing to do with success. These people are born into wealth, are wealth-adjacent, or are expert ass-kissers.
They also tend to be more greedy than others for wealth, status and power, and not imaginative enough to see that life is about more than this. So they dedicate their life to crawling up to the top of the corporate heap while everyone else gets on with actual real stuff.
People who are smart in one or two domains often overestimate how smart they are in other domains. They develop a mental model, confirm it quickly, and never re-asses it.
The issue with AI, is we’re probably hitting our first real S curve with the current technology’s performance but a lot of people who bet big are only see the exponential part and assuming there won’t be a level off, or that the level of is far away.
There is no Moore’s law for AI.
Being a CEO has absolutely nothing to do with intelligence, I guarantee you that Duolingo has employees who are far more intelligent than the CEO.
People keep forgetting that these companies’ product is stock price, not whatever they’re advertising at any given moment.
Their “CEOs” have gotten sloppy because the grift has gotten so easy they naturally assume everyone is in on it. If everyone is in on the grift, there’s no need to lie about it.
There should be a federated system for blocking IP ranges that other server operators within a chain of trust have already identified as belonging to crawlers. A bit like fediseer.com, but possibly more decentralized.
(Here’s another advantage of Markov chain maze generators like Nepenthes: Even when crawlers recognize that they have been served garbage and they delete it, one still has obtained highly reliable evidence that the requesting IPs are crawlers.)
Also, whenever one is only partially confident in a classification of an IP range as a crawler, instead of blocking it outright one can serve proof-of-works tasks (à la Anubis) with a complexity proportional to that confidence. This could also be useful in order to keep crawlers somewhat in the dark about whether they’ve been put on a blacklist.
Did you comment on the wrong thread?

I gotta say, the icon of Duo looking like this, plus a snot coming out of one of its nostrils is what did it for me. No way to turn off this “feature” either. I’m not easily grossed out, so seeing it once or twice would have given me a chuckle. Seeing it every time I opened my phone? Nope.
I knew I wouldn’t be renewing my subscription right there and then (there were other reasons, but that one moved the decision faster.)
wait what… they made the official icon look miserable and added snot? wtf?
Yup! Google “Duolingo snot icon” and it will be the first image result.

holy fuck
I think on iOS they added a thing where it would change based on the days you didn’t use Duolingo. Honestly at this point I think it speaks more about the sorry state of their company more than anything.
People are unfair with this “CEO”. Its statement helped me move on from duolingo, which has seen significant decline in quality while never going beyond “a moderately bad way to start learning”, toward better, more developed, more cared for, cheaper, solutions.
So, thanks for that.
Please do share :)
I’m mainly interested in Japanese, so I’m currently looking at www.renshuu.org . In addition to just throwing random stuff at you, it gots some more in-depth training, explanations of stuff (something that never happened in duolingo), additional hints for alphabets including some mnemonics, and years of dedicated experience in the language. I can’t tell how it would feel long term, but so far even having some basic explanations is a great improvement.
I’m not gonna lie, I stopped using Renshuu due to having other resources at hand and because it just looks so rough, but I think it’s great for a free resource. The fact that they offer a shit ton of vocab/grammar/kanji study sets for free and community built ones is reminiscent of Anki, and Renshuu also uses a SRS. Lots of customization for reviews and answer options.
It’s certainly nowhere as eye-catching and addictive as Duolingo is, so beginners are probably more likely to give up than if they used Duolingo. But honestly, that site lost the point of what learning a language was supposed to be about anyway.
Sometimes I feel I should pick it back up, but at this point I want to focus more on reading/watching content for practice/learning.
crazy how fast they ruined the reputation of this company. just a couple months ago, duo mascot and Duolingo streaks were cool and fun. they had a good thing going. but now it’s just another shit tech company again. they lost all the good will in like a month.
Twitter enter the chat
Twitter was going downhill hard already when Musk bought the place
I uninstalled yesterday, good riddance Duo.
FTFY: Pretends to walk back his statements. Fools no one.
except his AI.
So…tries and fails? 😛
Duolingo is one of those fad apps that are overrated but are exquisitely trash once you force yourself to use them just to say “Hey, I have learned a language!”. Honestly, it was pretty funny seeing Duolingo comment on videos on all that despite it feeling forced, replacing it with AI just signifies Duolingo’s slow and painful demise
