Is the Great AI meltdown imminent? A huge shift from Nvidia doesn’t bode well for OpenAI or Generative AI maximalism:

What will A.I's impact be on scientific research?

Melanie Mitchell Computer scientist
“I believe this impact will not be as rapid as many think. A.I. systems still can't do things humans are essential for, like asking the right questions, planning experiments and entire scientific programs, and understanding data in different contexts.”

“People are greatly confused about large language models, attributing a humanlike intelligence to mimicry machines that turn out to be superficial and unreliable.
Intelligence is about reasoning flexibly in face of the unknown, and large language models continue to struggle mightily with that.”

Hehe, quoting @garymarcus.bsky.social "if you care about the security of your device or the privacy of your data, don’t use OpenClaw. Period."

OpenClaw (a.k.a. Moltbot) is everywhere all at once, and a disaster waiting to happen Not everything that is interesting is a good idea.

OpenClaw (aka Moltbot) may have gone completely viral, but it is also a disaster waiting to happen.

A PSA for why you should steer clear.

The fundamental mistake of people like @chrislhayes.bsky.social is to ignore and fail to engage with the principled skepticism of LLMs by people like Ilya Sutskever, Rich Sutton, Yann LeCun, Demis Hassabis, Melanie Mitchell and myself that has been increasingly vindicated.

firing and incarcerating the officers who did this is not enough.

ICE is rotten from the top down.

yesterday’s murder wasn’t an accident. it was a culture.

Timeline: How the Shooting of Alex Jeffrey Pretti Unfolded A moment-by-moment analysis of video from the scene shows that Mr. Pretti was already restrained when fatal shots were fired, which appears to contradict the federal government’s account of the event.

Murder in broad daylight, by the U.S. government.

World models are necessary but not sufficient.

Pure LLMs don’t have them at all.

i of course have been pushing for them for many years.

"With the help of Meta’s media lobby he has succeeded in fooling most of the press and some fraction of the public. LeCun has lapped it up, and done absolutely nothing to set the record straight.

But the myths about the originality of his thought simply aren’t true." - @garymarcus.bsky.social
