That is not what they found. What they found is that if you spend 60 minutes doing the homework with AI, you learn approximately as much as someone who spends 60 minutes doing it without AI. If you spend 20 minutes doing it with AI, you learn as much as someone who spends 20 minutes doing it without AI. Etc. The only real difference is that the AI people get way better homework scores, and as a result, tend to stop spending as much time, and thus tend to learn less.

That's what this preprint study found.

100% this. Even a short 5-minute quiz with just a couple questions at the start of each day will do the trick. But you simply can't rely on homework scores to be a proxy of learning or time spent studying anymore. Brief daily quizzes on the previous day's material will force them to.

Also, It's not like students have the excuse of, "I couldn't study, I didn't have anyone to explain X to me" anymore. The very AI that they might otherwise use to cheat on their homework can also explain to them the things they missed in last year's algebra class that are blocking them from learning this year's calculus, or whatnot. Congrats - you now have an infinitely patient personal tutor who will spend hours dumbing things down for you until you get it. Now you have no excuse - learn the material. It becomes all about actually putting the time in.

Yeah. There's been widespread misrepresentation of this (preprint!) in the media. What they actually found: test scores correspond to how much time you spend doing homework, regardless of whether you use AI or not. Which should not be a surprising result! Of course, the AI people, esp. those who had been using AI for more than a few months, stopped spending much time on their homework, and then their test scores fell to match the non-AI users who didn't spend much time in their homework either.

The TL/DR is, in today's age, you cannot use test scores as a proxy of how much time a user is studying or knows the material.

There are of course some caveats, beyond the fact that it's just a preprint - notably that there's nothing to separate why the user started using AI to do their homework, so there's potential confounders in there. For example, if a student is in a poor family, maybe they had to get a job to help pay the bills. But working a job itself can lower test scores - for example, having to work late the night before an exam. So there are some confounder problems with the study. That said, I'm sure the general conclusion is correct: time spent doing the thing = amount of learning the thing (relatively independent of what tools you're using in the process).

Meanwhile I also own a Tesla, and am using a CarPlay adapter with it. Maps is better, particularly lane guidance and actually telling me which motorway junction number I'm coming off at. I can share an ETA with my contacts. I can listen to subscriber-only (paid) Podcasts. I can use WhatsApp (via voice of course), something sadly essential in the UK as the vast majority use that. I can listen to audiobooks from other than Audible. I can use the BBC Sounds app. I can...

You get the idea. I agree with you about integration - the time I will use the built-in map is if I'm on a longer journey that needs charging on the way, or if the journey is so short that none of the above really matters.

Personally I hope the rumours about CarPlay integration being worked on by Tesla are true, although I'd be surprised I must admit. But for me - works well.

I'd guess, but stressing guess and agree would need to be studied, that your bias would be correct. I'm not necessarily a fan of the every single person's study plan is different school of thought, and think there's a lot to be gained from structure.

On the socialising I'm not quite so sure though - it's definitely changed the nature of it though. My 'kids' (now all adults, youngest about to enter final year of university) socialising all the time on-line. Voice chats with friends, Discord is how they organise meeting up etc.. They've also all three kept a healthy in-person socialisation side too, which is the part I was initially worried by when I saw this panning out over several years. I think that last bit is key - if you can balance both, then you get the benefits of going out with your friends with also the benefits of having a wider geographical friend base and the ability to stay in touch more easily.

I feel like I'm in a constant race to flee enshittification : Used to use Cursor (it's still my only option at work), but then Musk bought it, and they instantly went in on hard-sell tactics. Switched to vscode + copilot + OpenRouter, but was getting concerned about API costs. Just yesterday I set up a Tencent TokenHub account with their Max package, which required that I switch off copilot if I wanted to be able to use some models like Kimi K3 (had a temperature=1.0 requirement, copilot doesn't let you set temperatures and hardcodes them to very low), so now it's vscode + Pi + TokenHub.

Sigh. Please don't make me move again...

(Not that Tencent is in any way "the good guys"... but they're also providing a very generic product)

Perhaps read the actual comment? I am agreeing with the study - quoted directly: ""The findings suggest that screen time can support children's and adolescents' cognitive processing. Presumably, the essential point here is what kind of things they do in their screen time. Teachers and parents should encourage children to use devices and screens in such ways that promote active thinking, problem-solving, creativity and learning," states Doctoral Researcher Petri Jalanko from the University of Jyvaskyla.".

Yes, it's nice to see a study backing it of course but this has been intuitively obvious for a while. The "screen time is killing our kids!" crowd is just the latest generational re-incarnation of the "computer games are killing our kids" from the 1980s, or "Dungeons and Dragons is killing our kids!" from the late 70s through the 80s, "TV is killing our kids!"...right back to Socrates moaning about writing. Just another moral panic.

Since we're in 80s mode, let's quote The Karate Kid: "concentrate on quality of what you know, not quantity". It's the nature of the screen time that's important, not necessarily the raw bulk. Are you interacting with people online, are you reading stuff? Are you watching some videos where you learn some things as well as just the latest cat videos or TikTok dance? In short, are you using the screen as a portal to the generalities of life instead of just watching brainrot all day every day?

I suspect knowing that will be key to whether the screen time is hurting or helping. And as ever, a balance is required. 100% screen and no in-person interactions is obviously harmful, provably so thanks to the pandemic providing us with data here. I'd also posit that 100% outside and in-person will be good, but not as rounded as a decent mix between the two since you gain access to different experiences online.

"It suggests" if you ignore that their confounder control is terrible. First, sugar wasn't the only restricted food in post-war Britain - there was also rationing of eggs, butter, cheese and meats that ended during the same timeperiod. So you're not actually testing the effects of sugar consumption, now are you? Also, the early 1950s was a period of rapid change in the US, including the maturation and expansion of the NHS (founded in 1948), the introduction of new childhood vaccines, major environmental shifts (for example, the Great Smog of London in 1952 vs. the 1956 Clean Air Act). Saying "all changes = sugar" just based on birthdate seems absurd.

It's also worth mentioning that there's also survivorship bias - anyone who died before the study couldn't be enrolled, and there's also no actual linking to any maternal / childhood dietary logs. Also, the ratios of cancer differences they're describing aren't small, they're massive. Are we to attribute a lung cancer difference on the order of smoking vs. nonsmoking households as being to sugar, or due to, you know, smoking (or pollution) trends not accounted for in their cohort?

Way to out yourself as being American by being simultaneously loudly, assertively ignorant and racist at the same time.

** - Collective guilt is a fallacy; modern Germany is a highly democratic constitutional state with a commendable record on teaching against extremism; Marx and Engel drew heavily from French utopian socialists (e.g., Saint-Simon, Fourier), while it was the Russians who actually implemented communism; World War I began with the assassination of Austrian Archduke Franz Ferdinand by a Bosnian Serb nationalist, triggering a chain reaction of ultimatums and alliances involving Austria-Hungary, Serbia, Russia, France, Germany, and Great Britain, with any individual state bearing guilt for the war being a notion firmly rejected by modern historians; Hitler was born in Austria-Hungary and was an Austrian citizen until he renounced it in 1925, not gaining German citizenship until 1932; the East German government and the Stasi was forced on the people of Germany by the USSR, and it was not a global phenomenon "brought to the world", but rather dissolved with the GDR in 1990. TL/DR: Go fuck yourself.
