As a server mod, there are real, obvious reasons you'd want to ban AI-generated content. And yet a lot of the no-AI rules I've seen in Discord, Mastodon, and Reddit feel like they have an anti-technological undercurrent to them, built more on fear of the unknown than actual understanding.
It reminds me of how people distrust processed foods, not for the sugar and salt content, but because they can't pronounce the names of the ingredients. There's a lot of overlap between that mindset and the whole vaccines-causing-autism crowd.
I'm afraid that reflexive, unthinking reactions to AI could cause anti-technology attitudes that hurt accessibility for people who depend on technology in their day-to-day lives.
