Yeah factoring is a crappy benchmark and its hardness is easily misrepresented. Quantum hardware is a long ways from actual demonstrations that show anything about the hardness of factoring.

I always like to be in the low percentiles, happy to see that there are less than 1% who give the obviously correct answer, retrocausality :)

I think I may have learned from Shuki that jokes and joy were a great part of teaching science and doing research. And all of you have suffered ever since.

Mumble mumble years ago I took two courses taught by Shuki Bruck at Caltech. I wasn’t great at attending classes, but he was such an amazing teacher that I attended every one of his classes. Watching the clips here reminded me of the joy with which he taught youtu.be/WEVZAgNZehA?...

Hirahara, Illango, and Loff posted on the arXiv a lovely result, showing that determining the communication complexity of a function f is NP-hard. A fundamental question first asked by Yao in '79. The proof is very clean and elegant. A fun read for the weekend!

The Shakespeare festival is wonderful and highly recommended (I was spoiled to grow up regularly going to shows there) I saw a nighttime production of A Midsummer’s Night Dream at the Elizabethan theater whose costumes were out of this world.

Had forgotten that it was an engineer in Hamlet who hoisted his own petard

β€œFor 'tis the sport to have the enginer
Hoist with his own petard” -Hamlet

Seems like tech bros have been at this game for a long time (to be fair, this old use of enginer meant someone more like a bombmaker)

One of the things I enjoyed about your book is that your subjects just hoist themselves in their own petards. β€œThese fucking people” is exactly right.

The point is ra-ra-ing anything AI tagged dilutes its real value: Travis claims AI is on the verge of discovering new quantum physics. I say bullshit is the right answer to this, not β€œyes but” speak that overhypes by not addressing the claim.

β€œScant evidence” – Google’s AI chemistry claims misleading AI discovered 2.2m new "materials" said DeepMind. Chemistry professors investigated, found hallucinations, repetition, known crystals.

When these hit the real world, people who know what they are talking about are not impressed www.thestack.technology/scant-eviden... EchoNet is nowhere near the topic of discussion: using AI for discovery, it’s plain vanilla classification not discovery.

β€œGo to the edge of quantum physics with GPT” and start free-associating without doing the math or proposing experiments, you’re not doing physics; you’re generating science-fiction brainstorming. That can be fun, but until someone does the hard yards, it lives in the β€œvibe sci-fi” bucket.

The idea that he would somehow know enough even to evaluate whether ChatGPT has come up with a potentially useful insight is laughable.

Faster than humans oh my gosh. Computers have never done things faster than humans. The words you use show a lack of any deep engagement. Which is sort of the issue here. If you talk to experts who actually know shit, you’ll be less impressed with your own technobabble.

That’s a lot of words that sound like they have insight, but are actually vacuous. What is an AI build (making me think you don’t understand what a build system is)? Unstructured is exactly where AI has struggled. What does the number of functions of an organization have anything to do with this?

I know it is probably a violation of Godwin's Law to mention this, but as far as I know the last program that tried to get millions of people to leave their homes to work on farms was the Cultural Revolution.
