Going into a community expecting human interaction and instead finding nothing but bots is like joining a game server only to find out that it's 18/20 bots. I think it sucks and it's not what I want. Frankly, if I wanted to talk to AI chat bots (and I really don't) there is already no shortage of places to do that.
I do worry a little bit that one day the internet will be so full of AI-generated garbage (words, images, music, etc.) that it will lose most of its value and utility to actual human beings. Centralized corporate social media already has a massive problems with bots and sockpuppets, and technology only seems to be moving in a direction that will make that problem worse. I'm sure the corporate parts of the internet at large will become majority bots sometime in my lifetime, maybe even in just a few years.
So, whether it's Mastodon, Peertube, Kbin or whatever, I genuinely think and hope that the Fediverse represents a small opportunity to keep mostly human communities alive and thriving, and so I hope that bots are used rarely and transparently, if at all.
