I perfectly understand what you're saying, and I think you're right; but how exactly do you filter what is written by an AI from what is written by a human? That is, how do we tell if a post was written by a human or a robot or AI? Is there a way to do it beyond any doubt?

Because if we can't tell it apart with the naked eye, we risk ignoring or penalizing content that was written by real people and not by AI. AI is gaining too much ground these days, and the entire Web (2.0 and 3.0) will suffer, that's for sure. The quality of Online content will never be the same again if AI ends up prevailing over common sense; but since humanity seems to be in a spiral of collective stupidity that seeks only what is easy, what is artificial and what is fast instead of what is well built, instead of what has solid foundations or at least, people behind it, then it is the safest , I think.
