It doesn't have to be. But it does get somewhat boring and trite after a while when you start noticing that certain subjects on HN tend to attract general and/or samey comments about $thing, rather than the submission topic within $thing, and I do think that is against the guidelines.

The specific part of:
> English is a terrible language for deterministic outcomes
Strikes me as both as a generic tangent about LLMs, and the comment as a whole feels like a shallow dismissal of the entire talk, as Karpathy never claims English is a good language for deterministic outcomes, nor have I heard anyone else make that claim.
There is a community expectation that people will know what they're talking about before posting, and in most cases that means having read the article. At the same time, I suspect that in many cases a lot of people commenting have not actually read the thing they're nominally commenting on, and they get away with it because the people upvoting them haven't either.
However, I think it's a good idea to do so, at least to make a top-level comment on an article. If you're just responding to someone else's comment, I don't think it's as necessary. But to stand up and make a statement about something you know nothing about seems buffoonish and would not, in general, elevate the level of discussion.
Particularly not a 40min video.
Maybe it is tongue-in-cheek, maybe I am serious. I am not sure myself. But sometimes the interesting discussions comes from what is on top of the posters mind when viewing the title. Is that bad?
