I think that if you had hiring policies that allowed people not to worry about whether they got credit for an achievement, you'd have people significantly more OK with transitioning to an "egoless" approach.

A few years ago it was discovered that LLMs can implement gradient descent in their processes. Producing a full trained neural network would be an extension of this.

Mathematicians both build/formulate abstract conceptual frameworks and formulate problems within those frameworks. Solving the problems has historically been one of advanced the conceptual frameworks.

Now, what has been useful for advancing physics and biology has been the abstract conceptual frameworks - using Hilbert Space for model quantum mechanics or tropical geometry for DNA modeling.

So far AIs have shown an ability to prove mathematical theories but not an ability formulate coherent-to-human mathematical models. So allowing AIs to simply replace mathematicians isn't so far a way to achieve broad advances in other fields. Indeed, AIs so far are great mathematicians only if one views mathematics as solving "meaningless puzzles ... in isolation"

I should say, Erdős was acclaimed but actually far from universally popular within mathematics. I had a professor who advised me to stay away from another professor because the other professor was a follower of Erdős.

Pre-AI, I think it's correct to say that math exposition was given short shrift (but to be fair, at least in the US, math education fell under the umbrella of education schools and teacher training rather than university math departments and so professors of mathematics often could do little to change the sorry state of math education even if they wanted to).

But, on the other hand, the construction of grand structures, frameworks unifying various math fields, was already a competitor of the problem-solving paradigm (and Erdős' approach was actually an extreme wing of the problem-solving wing and his activity shouldn't be considered an example of what even a significant minority of math professors did).

Math is toxic yet the least toxic?

I will stick to my claim that math exists in the context of the hyper-competitive overall academic culture.

I should add that extreme competition combined with math being something people love, something with beauty unto itself, produces an especially weird world compared compared to a situation in, IDK, business school, where everything is about the money.

I mean, asking "who deserves to live the dream" really twists people's heads.

AI hasn’t benefited the bottom line of any big corporations outside the tech industry

I am not an "AI booster", it seems like the current market leaders have dug a hole that they'll have a hard time getting out of. Just about everyone says something like "there's a bubble, it will burst, people will be hurt but the process will go on, like the Internet or railroads". But that ignore that the scale of this is beyond earlier bubbles (each bubble is larger than the last in our 30-40 year bubble-and-pop driven economy but that might not be comforting).

All that said, "some aren't benefiting" or "the average isn't benefiting" is a disingenuous argument if you want to say things are bad. AI companies have more of a real product people are paying than Google did. A large minority of companies (not all in the tech industry) are getting a boost. It's easy to say "the average is zero" when you exclude some. AI has boosted media companies that do a lot of transcription. Video generation serves half of advertising videos.

It may be a bit unhealthy to only identify yourself only with your vocation - there's also family, friends and hobbies. But it's miserable to engage in "work" for forty hours a week when it's something you have no interest in whatsoever. And it is very unhealthy to think most people should do that. If "work is just work", how terrible is that?

If the sum-total of the activities you engage isn't "you", what is? The things you buy? "Your" sports team?

Plus a hypercompetitive academic world is a pretty good explanation for people identifying only with their vocation - how else to do you get to the top except putting your whole self into the challenge?

Yes,

The example definitely shines. Doing something barely non-trivial is great since it gives a feeling for the language. I wish other language introduction pages would take note.

I feel like the hyper-competitiveness of academia generally is the elephant in the room.

The disaster for a problem-solution-oriented mathematician isn't that once problem-solution is easy they'll just switch to theory-explanation and machinery-building. It is that they will have to compete (and won't able to compete) with students and post-docs who've been doing theory-explanation and machinery-building for their entire career - and there are lots of these 'cause academic pipeline produces more people who can fill a job than jobs in every imaginable category and subcategory.

If you look carefully at the chart, US nurse salaries are high because US salaries are high. The ratio of US nurse salaries to average US salaries is nearly the same as the OECD average.
The exact profit margins of hospitals as a whole doesn't matter. Hospitals are where health care happens but financially, they are simply a platform for a multitude of other private entities which make profits on top of the simple hospital fees - the "Uber For Nurses" thing is just one of many ways this happens, you have everything from data management companies to separately own MRI machines adding to the patient's bill and having a voice in the management of the hospital.
Re:Mathematics has changed. Let's act like it on Sunday November 01, 2026 @02:26PM (#50328812)
The thing about much human progress on various problems is that human mathematicians formulate a human comprehensible machinery for the purposes of solving a given problem and then that machinery naturally suggests (to humans) further questions which then give rise to more machinery - And, in a sense, the value is ultimately the machinery, which has tended in the past to be relevant to physics, computer science, logistics, sociology and philosophy.

When AI writes proof no human can understand, it doesn't advance mathematics this way. Maybe AIs can understand their own proofs - meaning not just verify them but extract a machinery/broader-perspective (but I wouldn't count on it). But even machinery an AI isn't necessarily useful for humanity/society.

Why shouldn't utilities pay for this? You're provide grid load balancing. Theoretically their pricing should be considering this? It's not actually free to you since charging and discharging your battery costs money.

I’m also reminded of Ashraf Ghani, the last President of Afghanistan, who was a professor and wrote a book “Fixing Failed States.” He ended up fleeing the country like a coward as it collapsed.

Meh, no amount genius would have helped someone fix Afghanistan given that it was controlled by drug dealers abetted by the US state. I had a friend who was an urban planner, went Kabul on a grant and advised the state to put in sidewalks. Sure it would have improved things but naturally it didn't happen 'cause the state had corruption to do instead.

It's interesting you imagine nine shares would suffice for a large site like HN. No, the link doesn't work for me. Honestly, this kind of "sharing" seems a bit disingenuous at this point.

Re:StackOverflow now gets fewer than 1000 questions a month on Thursday October 29, 2026 @12:52PM (#50292149)
Wow, I didn't know anything of the moderator-interface-and-training details and this definitely gives the situation more clarity also.

Question-closing was a big complaint through-out SO's history. My guess is that the top people were unconcerned because someone who complained about it was by the way the system defined people, a bad user (since they were lumped-in with those who really did ask already answered questions).

Re:StackOverflow now gets fewer than 1000 questions a month on Thursday October 29, 2026 @01:51AM (#50284994)
Yeah, it makes me curious about exactly what thinking was involved in the site going to heck like that. Part of it was questions and answers accumulating and so the question of duplicates thus apparently weighing on the moderators minds more. Part of it might have been an effort to prevent people gaming the system.

Actually, talking to ChatGpt, I found this article: “Stack Overflow Isn’t Very Welcoming. It’s Time for That to Change.” ( https://stackoverflow.blog/2018/04/26/stack-overflow-isnt-ve...) and that actually shows what the SO admins didn't get (imo obviously).

They thought the problem was people not being nice. But that actual problem was that SO was "gamified" and it's gamified interface made it impossible to win unless someone was ultra-competitive (and I'd those types burned-out over time as well). People not being nice was real but it was side-effect of the situation (questions answered instantly so a would-be question answered had to be constantly racing).

It's easy to imagine how the admins didn't see the situation. Each up of intensity seemed to up the engagement and so seemed a good thing. The question of whether the process was sustainable didn't appear and when there were problems it was attributed to something else.

I think

whether the original authors would have produced their work without building off from the work of other mathematicians.

That's rhetorical, right? Of course mathematicians built on what older mathematicians built and OpenAI's machine built on that. The real question whether OpenAI's machine has contributed something others will in turn build on.

Re:Anthropic S-1 on Monday October 26, 2026 @12:13PM (#50246266)
Indeed,

The closer you get to the real or plausible "omnipotent genie", why would the person in possession of such a thing respect the rights of the formal owner - and why the engineers and operations managers respect the right of the management - this along with the question why the maybe-conscious super-intelligent machine itself would respect the rest of the hierarchy?

For now, these structures actually need massive resource inputs and that doesn't look to change soon but naturally one should be on look-out for the possibility of the tide shifting.

Bus Rapid Transit is neat but you don't need it to create a reliable public transit system. A smattering of American cities have had reliable and popular public transit system (Portland in the late 90s I recall). The problem is that good transit system get gutted whenever a city runs a deficit and so public transit converges to its stereotype - a slow moving, irregular single line filled with those not having a choice about riding it.
It’s a pretty normal concept that public transit is not a charitable program and must yield benefit commensurate with spend.

The benefits of public transit derive to all of society not necessarily those immediately riding it. That's true of a multitude of state spending, education, social services and so-forth.

The US doesn't directly charge for many of the costs of roads, certainly it doesn't charge for the drawback in the form of pollution and urban sprawl. But when you get to buses, suddenly "you're not a charitable problem..."

No you don't.

You need a state or other body committed to fixed routs and seeing their long term benefit. The American ideology that public transit must directly support itself with revenue is what has resulted the miserable transit system that we see today.

Edit: I should add that the ideology of transit supporting itself also corrodes the key idea of fixed, scheduled routs, high-lighted in the article. I know in the US that even if a town I'm happens to currently have a decent public transit system (an occasional though uncommon occurrence) I know it will be crap in a couple years as revenues fluctuate since local transit is a political football, so I'd never count on public by selling my car or other decisions.

Re:PhysicsForums and the Dead Internet Theory (2025) on Monday October 26, 2026 @11:34AM (#50245509)
The "Dead Internet Theory" is too sad and too easy. I'd propose the "Dead Society Theory", the history of the Internet from the late 2000s to the late 2010s left people socially scare, paranoid, angry and hopeless about the possibility of communicating online.

Which is to say the Internet can be "dead" without being filled with undetectable or detectable fake posts, not that fake posts help things.

Re:A Mathematician Reads the AI Future on Sunday October 25, 2026 @01:44PM (#50234039)
AI has already born out at this point. The question is no longer it's future capabilities but the impact of its present capabilities - though with its present capabilities, someone is now going to be pushing for more, at least as long present computer tech is widely available.
But AI "is really good, but not that good..."

AI's spottiness is exactly what describes this era. AI can create amazing code/image/video/article exception XYZ really annoying qualities that somewhat hobbles its ability to be autonomously.

And sure, maybe those problems will go away once we're at month X of the madness but we're still at month Y so are going to going remain for some moment.

The bulk of the safety should come from AI doing better job of reviewing tricky bugs since humans refuse to spend effort on writing more formal specifications.

But that part is the key point. We've had many years of networks building inherently insecure structures with security tacked as feature and the primary security process being more ad-hoc stopgaps.

Whatever one may think of AI, it's certainly showing the sh*ty shape normal cyber security is in.

I mean, the various supply-chain exploits we've seen said "we allow a dubious third party to blindly update our server 'cause it saves us admin money" and that speaks to how much other shoddiness a significant portion of companies allow on their servers.

It would be better if grant distribution relied on something saner than the effort to write a grant application, if education didn't rely the effort to write poor quality essays and servers didn't rely on the effort required to find the bugs you know are there. But those ships have sailed and I guess we're all just at sea.

My guess would be that "professional" essentially translates to consistent, reliable and structured in the fashion a given industry expects. In this sense, everything AI/LLMs do is going to be "non-professional". Even when they solve frontier level math problems, the mathematicians agree "this is a terrible proof" (this goes against how the field does things). These things is always inconsistent/unreliable/unstructured but sometimes not too inconsistent etc to be useful. "How do use" tip sheets are also going to a list of ad-hoc observations, many of which its easy to get after X many tries with the generator - but that OK, essentially what you want is ways to save yourself time screwing around.

These thing may reach your standard consistent at some point, maybe. It's not important since before and after this point, they will require "messing around" to produce something useful but they can produce something if you need "good enough" but if you demand actually good, they won't arrive ever.

If the model has a real consistent viewpoint that would be nice.

The problem might be that it simply looks at it's windows of what it previously and repeats that. But the original statement might be as arbitrary as the model that change their mind each time you challenge them.

Re:The Alien Space of Science on Friday October 23, 2026 @01:27PM (#50212487)
Something like the original computers, Eniac etc, were actually generally useful. It was useful to very large enterprises that previously relied on an army of human "computers" but it was useful for them so it stimulated refinements like the PDP-8.

I think if you went back in time you could pay some power loom engineers to build you a pretty decent 4-8 bit microcontroller operating at 1-5 Hz (comparable to power looms at the time) and computer-controlled textiles would have paid for the computer revolution 75-100 years ahead of time.

Would it? You have to remember that the further you go back in time, the cheaper labor is relative to machinery. In the 19th century, you could pay a person for a multitude of customizations and so the market for custom cloth might not have been what you imagined.
