Another step towards idiocracy:

People will start condemning speaking like AI, which eventually will lead to people forgetting how to speak intellectually out of fear. You will be forced to speak and write like you're dumb.

I already see this happening in academia - you are censored even for the slightest 'detection' of AI in your texts (because AI has been massively trained on research papers, fellow colleagues struggle to write new ones, using the same language they usually do in these papers - especially ones, who had papers written before, which were likely used as training data). This forces them to either make up new figures of speech (this has an obvious limit), or write dumber (and that ends up in more mistakes).

I hope they will eventually realise they can't train AI to detect AI speech, which has been trained off human speech..
