I can foresee a time when humans won't make qualitative judgements vis a vis human vs. AI. Over time the lines will blur as to human vs. AI content, we won't be able to differentiate between the two.
Given the way we are already prone to dehumanize others about more important things today, I have to agree that most people will run, not walk, to replace human artists with machines that pleasure them without getting tired. They will accept the AI text from their spouse, friend, or child and think, "Who cares if it's really them? As long as I'm hearing what I want, nothing more satisfying can be imagined or desired." That's the point at which jumping off bridges will be very popular, too.
