So was it really a passion project if it affects them anyhow? It's like saying that concept of dynamite fishing affects passionate anglers.

This is nothing like that. The disillusionment comes from imposters getting more attention and credit than the real thing. These shitty projects are nowhere near being superior to what a human can do, and most of them are blatantly lying and exaggerating their accomplishments. ie. dozens of "no emulator recompilations" that are actually just embedding an emulator into a binary with the game, and people are too fucking stupid to check and upvote it to the top of HN because we all love a good fraud here. Now this garbage can be mass-produced and get the adoration of the AI hype crowd, drowning out the content that people put hundreds/thousands of hours into despite the slop being of wildly inferior quality that doesn't hold up if you inspect it for longer than it takes you to click the upvote button. Not only here, but all over the internet. Of course it's demotivating.

He does say LLMs made things worse, even if he's not opposed to it.
