I think most small communities will stand bot-free because there's little incentive to have bot engage with it.
But I wonder if there's a size of conversation after which people will still choose AI assisted summaries. Discord had/(has?) a feature where it used LLMs summarize and then notify you about a discussion happening.
The Discord thing sounds like a reasonable and acceptable use case to me. Fuzzy search is basically the only thing LLMs are really useful for, and a feature like that actually serves the user. Help them find stuff that's interesting to them, instead of trying to replace it with a pale imitation of real thought and conversation. My most optimistic view of the future is that features like that will be what sticks around after the hype and bubble.
