I think a lot of great ideas like tree-width were developed in hope of simplifying the proof.

AI hits a "I'm Spartacus, and everybody else should be regulated" moment.

And tablets should have a "direct touch only, all options present mode" (no long-presses, no drags, no drags from edge, no swipes." It would really improve accessibility.

New comment by jmount in "Maybe Jacobian Conjecture Counterexamples Are Not Rare"

Unfortunately not. Most of my sampling ideas were too slow and not effective at high degree.

New comment by jmount in "Now is the time to give LLMs access to the ACM digital library"

Came to say the same thing. Now remains the time to give the public access to the ACM digital library.

I could not tell what parts the human author thought were phantasies they felt they had escaped versus which they really were wallowing in. Who honeypots the honeypots?

Why would they remain fundamentally expensive? It is a fixed machine (so eventually you recoup the investment) and running consumes nothing other than electricity and a paper gown. MRIs cost under $200 in Japan.

Thanks. I had some friends look. Half got it to work, half errored out.

I keep getting no server for fda.gov links. Anyone else seeing this?

New comment by jmount in "The case against geometric algebra (2024)"

jmount — Sun, 21 Jun 2026 17:39:13 +0000

My feeling on geometric algebra is that you should look too much into it until you exhaust the exterior algebra. That is (in my opinion): it isn't a good use of it to replace the cross product or specialized representations of 3-d geometric rotations. It is good for when you get a bit sick of the bookkeeping of the exterior algebra. From a computer scientist point of view it is sort of adding a bit of type information beyond just vector dimension and depth of product.

Thx, but looks like you are also getting downvoted. Sorry about that.

No point up-voting or down-voting this, already flagged off the site. Possibly triggered a controversy filter? I know the title is provocative, but it is actually the point the video is trying to establish (so it wasn't just ad-hominem).

New comment by jmount in "How to earn a billion dollars"

jmount — Sun, 14 Jun 2026 16:40:35 +0000

Not quite on topic. But I feel there is an issue in politics where many non-wealthy people vote as if they are "temporarily inconvenienced billionaires." That is they endorse policies that favor billionaires, as they have some hope of being one someday.

New comment by jmount in "Anthropic apologizes for invisible Claude Fable guardrails"

jmount — Thu, 11 Jun 2026 17:35:02 +0000

The whole arc was brilliantly evil. Once they put int the guardrails then Claude is fully un-falsifiable, and failure can be claimed intentional.
