Normies love this shit because it makes them fit in the crowd effortlessly. Same reason why corporate slop was a thing even before AI.

Personally, when I message people I respect I either don't use AI or ask it "please fix typos only", but if it's someone I don't give a fuck about, then AI-generated slop it is, because assuming that the recipient is a random person, AI-generated slop has the highest chance of actually getting shit done.
