One of the worries is that it will soon be impossible to know what's real and what isn't, at least when you're looking at a screen.
E.g you could have a zoom meeting with someone and not be able to tell if you're interacting with some kind of deep fake visual/ chatbot combination.
Also, AI can create graphics, write music, essays etc etc that are pretty much indistinguishable from human output. It may seem trivial but it has all kinds of implications.
