I don’t care about Newgrounds dying specifically, because I never go there. I do care about communities on the internet dying in general, because, well, there are communities I like.
This has nothing to do with AI specifically. Communities die because they’re overrun by people who choose not to follow the rules of that community. Posting AI content where it’s not welcome is just one example. Commercial spam is worse. Trolls are another example. It’s been a problem since the start of the Eternal September. Fighting back against this tide on the open internet requires human moderation. Automated measures exist, but all of them suck. AI-based moderation is just the latest example of an automated measure that sucks. It’s not (just) that I am opposed to AI on principle, it’s that AI does a terrible job of moderation. At least the old Bayesian models weren’t prone to hallucination.
The only solution that actually works is invite-only communities. That’s the direction the good parts of the internet are headed while the rest drowns in filth.
