Yeah, I'm pretty sure the vast majority of those "no AI" forks will die very quickly. I mean, what is even the best case scenario? The fork is on life support with some bug fixes maybe? Because I do not believe it will get more development than upstream. Besides, upstream developers will be able to take any new development they want from the "no AI" fork but obviously not the other way around.

I'm not an AI-bro but I think it's completely unrealistic to expect you will be able to avoid software developed with AI assistance nowadays and even moreso in the future.
