I don't think that's really what's going to happen... People stuffing puns in just to convince you it's human written just sounds silly. Not to mention you can ask GPT to do that too lol

What's going to happen is that branding will get more and more important. People simply won't trust anything from random sources anymore like they do now when they search on Google and treat the top pages as the truth

They will get most of their info from trusted sources/brands and filter out the rest
