Many students experience math as pushing around symbols that don't really mean anything. If that's your experience of math, maybe it's hard to viscerally get mathematician's complaints that a lot of AI proofs "only" solve problems, without generating any new understanding.

Which is not to say that we can't gain understanding from AI proofs or work. But "math is for deterministically generating correct answers" is a very different take from "math is for understanding why certain things must be true". Most students experience the first; most mathematicians the second.

Found myself wanting to say that "consuming text is easy and passive, unlike video which requires active effort to watch" and then realized this is the opposite of what basically every other human being would say.

His answer: we don't engage with the world as it is. We engage with "pseudo-environments", simplified pictures of reality we construct from the information available to us. We act on those pictures as if they were the real thing.

The number of students who attend my office hours absolutely cratered a couple years ago. At first I assumed it was just a slow semester but it's been consistent. I assume that instead of asking me questions, they're asking ChatGPT instead. Not yet sure if that's a good thing.

Starting to feel about autocomplete the way my parents' generation did about GPS. If I don't have to type my credit card number in every time, or my girlfriend's phone number, how am I gonna memorize it? That used to just happen, but now I need to actively drill it.

Have a lot more sympathy for all those people scheduling meetings that could have been emails, now that I regularly get complaints that my emails should have been meetings.

So all this "what are you going to do with a degree in X?" handwringing is sort of nonsense. Unless you know you want to go down a pretty specific technical career path, your undergraduate major just does not matter that much. Which I wish we conveyed to students better.

I am stealing “Elephants are big!” “No they’re not, they’re grey!”, thank you very much.

Realizing I resist critiques of algorithmic short-form video because they make me feel smug and self-satisfied and I don't trust that. I have zero interest in short-form video _or_ algorithmic feeds; judging them as also morally unvirtuous feels self-aggrandizing.

I have a deep aversion to algorithmic feeds in general; reading a post that was suggested by the algorithm feels viscerally bad. Sometimes I catch myself thinking "I wish I could read that story but it comes from an algorithmic feed so I can't." Silly—but a good antibody maybe?

I haven't seriously used a Windows computer in like a decade, but my personal laptop died and my employer gives me a free work laptop, but won't install Linux on it. So I'm seeing if I can make this whole Windows thing work.

If you have a sufficient critical mass to actually topple the regime, then by all means, optics don’t matter anymore. But until then, that’s what protest IS. It’s an exercise in optics.

You aren't fighting for his base, you're fighting for the loosely attached folks who are why you won by 5 in 2020 but lost by 1.5 in 2024. Like, I can't stress enough: the country is not 50% MAGA base and 50% progressive - there are a lot of 'persuadables' and you need them angry at Trump.

Also, I should note, I am saying that in this circumstance forbearance is *effective* which isn't the same as saying it is fair or necessarily just. It is the shortest road to a just outcome, but true justice will need to involve some accountability for many of these ICE goons.

Jay Daigle reposted

From a strategic standpoint, it seems important to remember that the 'center of gravity' of a protest movement is not control of the streets, but public opinion. The challenge that creates is a common strategic challenge: the emotionally satisfying thing is not the effective thing.

Social scientists have professional incentives to focus their work on what is _novel_ to people in their field, who they view as their core audience. The mental switch to be made is that what is _obvious_ to people in your field is often not obvious to ordinary citizens, and hence is valuable.

Unironically they should buy up the domains for about 60 defunct local newspapers in swing states. Hire two reporters to write almost exclusively about highschool sports and new restaurants opening with every 10th article about how the local GOP is screwing over people.

Folks are going to say, "well, they were (legal) immigrants" - but if the administration is packing people off to a foreign slave-labor prison without due process, you, me and the public have exactly the same evidence that they're not citizens as you do that they are gang members. Which is none.

On a daily basis, I marvel at how many people in putative positions of power are willing to help obliterate American democracy. The US has faced a series of very easy moral tests in the past decade and it’s staggering how often people in once-respected positions have failed.

I think the academic community can help US academics, as well as academia in general, by providing safe haven for datasets that are being targeted by the Trump administration.

Trying everything - and forcing them to bust every law and norm - helps you set those conditions. And also, like, there's some small chance that the norms hold and you avoid violence, which you *really* want to do. You *really* *really* want to avoid violent scenarios if at all possible.

Replying to @bretdevereaux.bsky.social

If you think this is going to end with mass protests in the streets or - heaven help us - large-scale violence, then your focus needs to be setting the conditions so that when that happens you win. And the conditions are: very low admin. legitimacy and popular support, engaged and enraged public.

I hope more people come to understand this. Life equips us with certain categorical boxes like “intelligence.” When something like LLMs appears that requires a new box, we would much rather stuff it into one of our old ones, no matter how bad the fit.

1. @alisongopnik.bsky.social, Cosma Shalizi, James Evans and myself have a new piece in Science on "AI" Large Models, pushing back against much of the collective wisdom about what they can and can't do. Official below, unpaywalled at henryfarrell.net/large-ai-mod... . So why this now?

my actual unironic advice to undergrads is to major in something you're actually passionate about/interested in, and then try and *minor* in either CS or stats. you would be surprised how how much being the person who knows a substantive thing and can do some basic computer/stats stuff can pay off

Those who know me know I was highly critical of what I saw as some of the rhetorical excesses of the campus protests. Khalil and I wld probably get into a spat immediately. It's all the more important for people who believe as I do to say clearly, the protections of the law are for everyone.

For those playing along at home, ideally for a good letter: 1) You have taken more than one class with them, ideally at least one of which was a small (35 students or less) course. 2) You have gone to office hours at least once. 3) You have discussed your career plans with them.

One thing I wish was explained to undergraduates more clearly is how letters of recommendation work and what they need to do in order to develop a stable of people who can write strong letters. Cause, like, if your first email to me - ever - is a LoR request, that's not a good sign.

'Learning to ask the right questions' is basically the entire purpose of education and training.

Mark Cuban@mcuban.bsky.social

If you have zero education, but learn how to ask AI models the right questions , in many jobs you will be able to outperform someone with an advanced degree, but who is unwilling to use Large Language Models. Just takes a smartphone, curiosity to experiment and a mindset to learn.

Too many people on here seem to believe there are exactly two kinds of Americans: ardent politically-obsessed Bluesky users, and frothing MAGA cultists. There are a LOT of people in this country who *just don’t pay a lot of attention one way or another*. And we absolutely can reach them.

If you want to meaningfully cut federal spending, you need to tackle defense, social security, and healthcare outlays. What they’re doing is structurally radical but sort of trivial as cost reduction. Some of it is likely to be more expensive in the long run.

The UK gov't has long tried to kill encryption. It's capitalizing on DC chaos to force Apple—and, shortly, all other tech companies—to build backdoors into their services without the USG objecting. Everyone—from Trump to Brussels—should speak out. There's no online free speech without anonymity.

In hindsight I think a generation of scholars and activists made a massive mistake in assuming that the conditions of (a, yes, deeply flawed in many ways) liberal democracy as the floor, the worst things could get, and so felt free to portray them in worst possible light. Whoops!

All of this from @pastpunditry.bsky.social. The crisis is not *legible*. Even politically attentive people have no idea - the media are not conveying the scope and magnitude of what's happening. It has to be made legible through political and institutional resistance, not passivity and resignations.

One of the most overlooked details in Atlas Shrugged is that significant villains are _also_ industrialists and that’s another way this “dream” falls apart. These bros _think_ they’re John Galt or—worst case—Hank Rearden but they’re more likely to be Jim Taggart or Oren Boyle (and not know it).

Kind of weird to me how little in the way of mass protests we're seeing. I'm usually a protest skeptic but this seems like exactly the situation for it. Trump is doing things that are (1) bad, (2) unpopular, and (3) illegal. That's the ideal case for protests to make progress!

I think there's a substantial boy-who-cried-wolf effect going on in AI now. If you try out AI and it's not very good, especially if that happens a couple of times, you learn it's not very good. And that belief sticks even if/as it improves.

A couple years ago I tested out using chatGPT (3.5) to write calc tests. I was unimpressed. (after already being sick of discussing gpt2 in like 2021.) I'm sure it's better now, but it's hard to convince myself to try again when it was so bad previously! jaydaigle.net/blog/writing...
