It'd be an excellent joke to not fix it

I think that is the joke, Implying most of the HN content nowadays is AI generated.

So at the moment https://g105b.github.io/hacker-news-with-ai-filtered/ shows no posts at all, which I presume is because of the 404 of the js file.

But you have to admit, it’s a pretty damn effective way of ensuring that no filtered posts make it past the filtering. By simply not displaying any posts whatsoever :^)
