I generally agree with the points, trust on the internet has eroded to zero and we need to invent new institutions to regain that.

But this subheading "Does it matter whether we know AI was used?" is just sad. There should be a space left for people who want to do stuff without AI. Niche, probably, but still. And this is why we should try to create ways to prove that stuff wasn't made with AI - that too will probably be based on compounded trust.

In the same fashion as people don't like watching chess players cheat, people will want authentic live music, and authentic art imagined by a human. At least I will, and I know I'm not the only one. Of course there will be bad actors that cheat, but once they're caught, they're not beating their allegations (see: Hans Niemann's stigma).
