10-15 years ago HN was the place where everyone showed off their new shiny toys and people would jump over themselves to try some new framework or db or tool. Now, so much negative sentiment about AI coding. I bet if LLMs came 15 years ago, HN would be brimming with excitement. What happened?

You should be critical. If you made something, you should proof that it works. Especially in todays world. This article contains no proof that their work actually works.

Except that all of it is open source and you can go try it. So this is basically me saying "I made a really nice cake, here, try some" and you're plugging your ears and going "lalalala can't prove this cake is good, lalalala it's shit".

How can you say it's a -really- nice cake without ever having tasted it?

The difference is that CEOs fired a lot of people, using "AI can replace human coders" as an excuse. Also: there are claims all over the headlines along the lines of "We built something amazing without human coders."

Both claims are loud and are flooding the discussion, but under the hood it's mostly a slop disaster.

So the negative sentiment is a natural response (and a dose of realism).

Mix in exhaustion from previous hype cycles (NFTs?) and folks pushing the narrative that if you currently write any code manually, you’re obsolete and it’s hard to not want to push back negatively. Even if you find the tech interesting/useful.

Oligarchy.
