They can, in theory. But when the signal to noise ratio gets too low, it becomes prohibitively difficult to filter out the garbage. Thus I don't think it's true that more people creating things is a pure benefit. It may not even prove to be a benefit at all, on net.
Same as it’s always been. Test the waters until you find someone with a consistent preference that lines up with your own. Personally I don’t really care if a critic is ai as long as its preferences are consistent and align with my own. If you dont find yourself relating to a critics take the great thing is that it’s easy to switch.
