openai dumping those 700 papers is identical to those data labeling "help us train ai models and we'll pay you between $50-$100/hr" firms except they're not even offering any money. It's lowkey disgusting. i've done data labeling in the pre-ml age for a google search contractor: it rots your brain.

“We’re now expected to either (1) check all this garbage that OAI is producing or (2) concede that all of these conjectures have been proven,” one algebraic topologist wrote to me. “I believe in politics this is known as ‘flooding the zone.’ We simply don’t have the resources to correct the record.”

I am wondering about what is meant by the observed data likelihood, in the ising model you have two discrete states but the N particles involved makes maximization of the systems likelihood a 2^N évaluations ordeal, that's if we don't use clever algorithms.

human doctors for me and doctor agent for you. I'm sure proponents will argue that "shortages" mean we must consider alternatives to human doctors in places where the ratio of doctors to people is very low. It side-steps the real cause of doctor shortages and I am not sure this is a good solution.

Not having those expensive to produce battles mean they have to spend more time making this writing hit and I welcome that. I am more annoyed when it's the opposite with lots of explosions and bad writing.

I am guessing that usage is growing at a pace which offsets the revenue loss due to price drops, which can explain how in aggregate they are increasing revenue.

interesting that I feel like the xbox 360 was massively successful and they somehow found a way to bottle their win and nobody at that company has figured out a way to center gamers again (as opposed to corporate interests)

A small but very bad quality of life change: google scholar used to offer the cite button for every version of a paper where there are multiple versions linked. Now (as per picture) it only does it for the top option. And sometimes the top option is the wrong one, rendering it useless.
For DePaul's paper "Phenomenal conservatism and self-defeat" the first version just says "Jstor" while the second and third give the actual citation to Philosophy & Phenomenological Review.What you see if you click through to the "cite" bit of the DePaul paper; useless  because lacking journal info

Beautiful article about math and AI by Dan Rockmore. The connection to art and photography via Walter Benjamin was very fresh -- definitely worth reading, even if you're tired of reading about math and AI.

Another day working in AI Safety at a frontier lab. Everyone asks me if they can use the model without it hacking into the UN. Buddy, they won’t even let me use the model without it hacking into the UN.

Students sometimes ask me if it still makes sense, in this accelerating age, to pursue a PhD in AI. Perhaps counterintuitively, I think it's a great time to do so. I wrote up some thoughts on this here: web.mit.edu/phillipi/www...

They quickly got rid of the semi automated system put in place during the Biden administration to file your taxes directly with the IRS if I remember correctly. The issue is only partially technical, it's mostly political.
