Them: We need a modern Bell Labs. Me: It's called Google, they invented all the AI stuff. Them: ...But Google didn't even profit off of the stuff they invented! Me: ...Tell me what you know about Bell Labs...
@MeekMill From the first moment I learned about AI I was like “Meek Mill is uniquely positioned to develop this technology.”
"Why do we need to import all these scientists when we should be educating our OWN people" -- guy who could never learn how to diagonalize a matrix even if he had 10 years to study
@Noahpinion Remember when the FBI/Army accused Qian Xuesen (co-founder of NASA’s JPL) of being a communist during the Red Scare (with 0 evidence), then deported him to China where he became the founding father of China’s aerospace and missile programs? Seems we may never learn this lesson.
After thousands of papers on meta-learning, the approach that ended up being successful (ICL) was an accidental byproduct of language modeling. Serendipity at its best and a good reminder that research needs to be open-ended and pursue a diversity of goals to escape local minima.
The German education system is insane basically at 12 they decide whether you can go to university or go to Idiot School and graduate at 15

Yep, this is a home run talk. Very nice work -- comprehensive and contemporary.
I'm shocked at how poorly this is advertised, so here's a PSA: NSF has a GRFP-like program specifically for computing disciplines called CISE. The program provides the same 3 years of PhD funding PLUS a year-long mentorship program for the application cycle.

This book articulates something I’ve fought for my whole career: goals and team metrics lead to mediocre outcomes. Actually novel work must be exploratory.

Adam Raine, 16, died from suicide in April after months on ChatGPT discussing plans to end his life. His parents have filed the first known case against OpenAI for wrongful death. My latest story on the psychological impacts of AI chatbots: nytimes.com/2025/08/26/tec…
