I see a lot of oss forks in the future where people just fork to fix their issues with LLMs without going through maintainers. Or even doing full LLM rewrites of smaller stuff.
I assume that most of these purely llm generated unwanted contributions will just end up in dead end forks, because my impression is that a lot of them are just being generated as GitHub activity fodder. But the stuff that really solves a problem for a person - eh, good. Problem solved is problem solved. (Unless it creates new problems)
