Currently AI is actually replacing some of these jobs. But there's kinda a hitch there - when you target me with ads or show me your company's website and it has obvious AI art I tend to think that you're either selling me something very low quality or are a scammer. If you show me the novel you've written and it has an AI art cover I assume the contents are also AI generated garbage writing. So I wonder if those jobs will really be replaced? It all depends on society's acceptance of AI art and if AI art doesn't get any better. I thought it would get to the point that I couldn't tell it was AI by now, but so far it hasn't.
I think AI waifus and porn and memes and browser based zynga type games will be a place AI is going to be accepted because nobody cared too much about the authenticity and quality of those things before either. But an advertisement selling me a car? The cover of a book on philosophy? A website that I'm going to give my credit card number to? I'm not sure about those things.
