AI does seem to “know everything”. … but it can only handle events it knows about. New problems will be outside its reach.
So yes, sites with unique requirements will not be servicable by AI alone.
I see it more as AI helping with drudgery. For example who , in Debian , sits down and tests that versions of each of the 50000 plus packages are compatable with all packages and the kernel.?
I think AI could help with something like that.
