I have some sympathy for these kids. If LLMs were around when I was a student, I would've also used them to "speed up" my homework assignments then proceed to fail all my tests. Now I work mostly with PhDs who were at the top of every academic environment they've ever been in. And yet I can see their thinking skills rapidly declining as well; many of them can no longer brainstorm, code, think deeply, or write without…

This is also why AI isn't going away. People will (and already are) leaning hard on it, and will pay in the future for that crutch.

“ However, when looking at muscle, once you have it you don't need to use it as much in order to maintain it” No.. this depends on how much muscle you have. The appropriate comparison is mass and density of knowledge/understanding vs muscle. There’s not a chance in hell you will retain mass and dense muscle without pushing the body hard. Just in the same way you will not retain very deep understanding of things unles…

To maintain the muscle you have, you only need about 1/3rd of your normal workouts. It can be retained with 1-2 workouts per week. I imagine the same would be for something you've learned. If you've already put in the effort to learn it, reviewing it ~1x per week is probably enough. During the accumulation phase though - whether it be muscle or learning a new skill - once a week is definitely not enough.

Yes, this is my experience for muscle at least. I used to work out 3-4 times a week, maybe a little more sometimes. Lately due to circumstances, I've been doing smaller workouts about 1-2 times a week. I've lost some finesse, but my muscle mass has remained roughly the same.

Also like some people hinted at this in sibling threads, I think it's different between purely abstract skills, and skills that involve muscle memory. For instance, I could probably stop using my bicycle for a very long time, and still not unlearn how to use it, or learn it again really quickly. Maybe it is because abstract skills are inherently more complex and require more cognitive effort and connections to knowledge overall, and are therefore more fragile.

We have to normalize being on silent all the time and making people wait hours for a response. Return to the primordial monkey of 1800s-era high-latency comms. At first, some people will be offended. "Why didn't you let me ping and buzz you and interrupt you all day? You didn't respond immediately each time :'((". Some people with unrealistic expectations may even stop talking to you entirely. But eventually (years m…

I've told people this for years. The mode of communication reflects the urgency. If you text me, expect a response on the order of 3+ days. If you call, and I recognize the number, it will be more urgent. If I DON'T recognize it, it goes to voicemail and back in the 3+ days queue. If you show up at my door, it is immediate. Even with my wife, she will text while I'm at the grocery to pick up some extra food items, an…

The current trend seems to be switching the priority order of calls and texts among many of us. I feel like a call should be scheduled, preferably 3+ days out, and preferably with an agenda attached. (Same rules I feel about any sort of meeting.) But a direct text (non-group chat, just to me) is a priority. Group chats get that 1-2 days middle ground.

>(perhaps guide them how they can use them professionally) If that's anything like how they guided me to use programming languages professionally... In my workplace I find systems and policies move too slowly to keep up with how rapidly the LLM world is changing. Colleges are even more glacial. They've barely adapted to video conferencing.

Yes, meanwhile, Claude Cowork was only released this past January. And that was amazing. But I don't know about anyone else but I've already moved on to just using Codex for just about everything (except some Kagi use). Schools work on timescales of years, AI is advancing on the timescale of weeks and months. Until that situation stabilizes I think the only institution capable of teaching about it is the family -- pa…

I'm not sure parents have the right tools either. Microsoft is about to ship OpenClaw as part of windows (talked about at BUILD) and they're acting like it's production ready and they've solved the security issues.

I don't believe them for one second, it's far from a solved problem yet these companies are selling this tech as if it's been around for decades and thoroughly battle tested instead of highly experimental and unstable.

Reminds me of this asian professor getting blocked for promotion, allegedly, on the basis of race, but in a roundabout way. https://www.msn.com/en-us/news/us/professor-sues-texas-unive...

Yes, they falsely classified him as white in order to deny him the promotion (because discriminating against white people is 100% non-controversial in that environment)

I think it's just indians being racist. The person could've put any other non white category and it would've happened.

> Many of them can no longer sit quietly for even 30 minutes just thinking on their own Plummeting attention spans has been a trend for much, much longer than LLMs and is more the result of constant digital interruptions and these days overwhelmingly social media and doomscrolling: https://www.apa.org/news/podcasts/speaking-of-psychology/att...

In 2002 I spoke with a lecturer in the humanities and he told me about how nobody was learning French at university level (in the UK). My own course had been cancelled due to the cost of teaching it, and the era of 'easy degrees' had set in during the early 90s. Before that, I also noticed the decline in newspaper readership in the 80s. It is easy to blame this general decline on the latest tech (or moral panic), whe…

I think we are talking about two different trends that have similar symptoms. I do agree there has been a noticeable anti-intellectual trend for a long time, especially in the West. (See also: Grade Inflation.) But that is separate from the drop in attention spans, which is relatively recent has been pretty strongly linked to digital stimulation, constant multi-tasking, and now short-form social media.

LLMs are an entirely new dynamic with significant cognitive implications, but I fear it will be hard to discern their impact from the falling attention spans and other long-term trends that have led to things like grade inflation.

How do we know this is due to AI usage? Perhaps it is because the students missed key in-person learning at the tail end of high school due to the pandemic lock-downs? I cant imagine learning calculus / linear algebra on my own in high school.

> I cant imagine learning calculus / linear algebra on my own in high school.

I don't think they necessarily expect students to have that from high school, because the class mentioned, EECS 127, lists three college classes as prerequisites:

* Math 53 - Multivariable Calculus

* Math 54 - Linear Algebra & Differential Equations

* CS 70 - Discrete Mathematics and Probability Theory

I’m not noticing the decline in my own abilities any more than I had before using them. I finished undergrad 20 years ago and my once sharp math skills had been severely diminished within only 5-10 years. Just simple arithmetic and percentages that I could rapidly do in my head became dependent on calculators/spreadsheets. For all other trivia type knowledge, my brain has offloaded it to the internet RAM in my pocket…

Congrats your getting older. Welcome to the club. Find hobbies and keep them, it doesn’t matter what they are it’s important as we age.

> It didn't just suddenly materialize. A sudden materialization is what's depicted by the data. > It's been steadily getting worse. I don't believe this is accurate. Failing grades are what the observation entails, and the data clearly depict an abrupt change; not a gradual one. In the section titled "Failing grades in 3 CS classes skyrocket in spring 2026 ", there's a clear jump in failing grades for all cited cours…

The jump is very likely due to AI usage and lack of skills in mathematics. It seems like prerequisite classes are not being fulfilled. "Ranade said students are expected to enter the course having taken classes on linear algebra, vector calculus and mathematical proofs. However, she found out in office hours that many students struggled with linear algebra, and was even more shocked when one student told her the line…

> It seems like prerequisite classes are not being fulfilled.

FWIW I did a little digging, and EECS 127 indeed has explicit prerequisites of:

* Math 53 - Multivariable Calculus

* Math 54 - Linear Algebra & Differential Equations

* CS 70 - Discrete Mathematics and Probability Theory

This suggests the students are either taking those classes or have provided some kind of AP/test-taking credential to skip them.

I know that's the trend, but it is backwards to me. Like UDP vs TCP. If you need an immediate answer for something, why send a one-way communication where you have no idea whether the person on the other end A) received it, and B) acted on it. A 15 second phone call accomplishes this, whereas if I text you it could be hours, unless you immediately respond.
