I've never heard about that nobody before, but I've watched about 10 mins. of the first video you posted and it is a terrible critique to Sabine; it actually makes Sabine's points look reasonable.

He just doesn't get the arguments she's making, and "defeats" them with laughable strawmans. But anyway, it's YouTube science so one shouldn't expect much.

Btw, Sabine's video on the topic of this thread is a good one, the remark is unwarranted.

> Professor Dave's videos on how Sabine Hossenfelder is actively contributing to an atmosphere of anti-intellectualism

I feel like the core of intellectualism is accepting criticism, including criticism you disagree with. I find some of Sabine's videos to be a bit click-baity, but they are usually logically coherent, even the ones that aren't convincing. She's not just a crazy person yelling at the sky.

Science is not religion. Its ok for people to feel certain research programs are off track. That doesn't neccesarily mean they are right, but its ok to have opinions

Interesting, her videos have never struck me as contrarian for the sake of it, she seems genuinely frustrated at a lack of substantial progress in physics and the plethora of garbage papers. Though I imagine it must be annoying to be a physicist and have someone constantly telling you you're not good enough, but that itself is kind of part of the scientific process too.

My biggest complaint is sometimes it seems like she will take some low quality paper and just dunk on it. This feels a bit click-baity/strawman-y if nobody was being convinced by the paper in the first place

[I am not a physicist so probably can't really evaluate the whole thing neutrally]

IDK why I'd want to listen to physicists about this result, which is mathematical rather than physical or scientific. John Baez, sure, he's in the intersection between math and physics. But physics in the broader sense is an empirical science where truth comes from experiments. This result is the opposite of that.

Not enough em-dashes for it to be AI. (Less jokingly, nothing strikes me as particularly AI about the comment, not to mention its author addressed the question perfectly adequately. Your comment comes off as a spurious dismissal.)

To me, it looks like AI because it doesn't really answer the question but instead answers something adjacent, which is common in AI responses.

Giving a short summary of Hilbert's biography & his problem list, does not explain why this particular work is interesting, except in the most superficial sense that its a famous problem.

Prof. Sabine Hossenfelder is a pretty clear-headed communicator. I've been following her for nearly 20 years, almost since she started writing the Backreaction blog. Her criticisms boil down to: 1. Modern science spends perhaps too much time on frivolous research that doesn't lead to anything. This very much applies to the theoretical physics and the endless series of attempts at ToE. But it's not limited to theoreti…

The challenge is that she’s right on all three of these major points … to some extent. Unfortunately at times she seems eager to fling babies without even encountering bathwater.

Your second paragraph is a much more thoughtful critique, and posting that below the original answer would focus the subsequent conversation on those points. The issue here isn't whether the comment was AI-generated; it's how we carry the conversation forward even if we suspect that it is.

(For the record, if I had attempted to answer the earlier question, I probably would have laid out a similar narrative. The asker's questions were of a kind asking for the greater context, and the fact that Hilbert (mentioned in the submission title) posed the question is pretty important grounding. But, that's beside the point.)

I think the last sentence, about Shelby and Miles, was written by a human, because it doesn't fit with the rest at all. Different style and a complete awkward shift of gears non sequitur. He probably recently saw the Amazon movie Ford V Ferrari, and so he threw that in to feel like he was doing more than cut-n-paste from an AI.

may you please elaborate on why it is important, why hasn't been solved before and what new applications may you imagine with it, please?

Explained for the layperson in the video cited here: https://news.ycombinator.com/item?id=44439593

That video s very light and doesn't explains at what point (or intuitively) where the arrow of time comes in.

But you cannot prove it. So what value did your comment bring? The readership of this site should always question if a comment is in good faith, legitimate, and accurate. Your commentary may only be one of those.

> But you cannot...

Prove it. Prove I cannot.
