While this is good thing, not being able to tell what is real and what is not would be disaster. What if every comment here but you were generated by some really advanced ai? What they can do now will be laughable compared to what they can do many years from now. And at that point it will be too late to demand anything to be done about it.

Ai generated content should have somekind of tag or mark that is inherently tied to it that can be used to identify it as ai generated, even if only part is used. No idea how that would work though if its even possible.
