The problem with copywriters is that they wrote "copy" - which turns out to be writing that I don't want to read. And the problem with AI is that much of what it trained on is copy, so it trained to write stuff that I don't want to read.

So in the end, I don't care if a human wrote it or an AI, I don't want to read it either way.

What's wrong with copyrighters? They write like corporations, not like humans (see the Cluetrain Manifesto for more on this). They sound like nobody - literally inhuman. I don't want to read that. I want to hear a human voice. If I can't hear that in your writing, I don't need to read it.
