Why HN links it

Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
> reading code, understanding, hypothesizing, comparing, ...identifying problems and proposing solutions, and more Except it did none of those things, really, because that's not how it works. This might help, it's a good writeup: https://www.0xkato.xyz/how-llms-actually-work/ We know how these machines work, it's not mysterious, there's nothing "extra" happening.
