AIs are never going to get the tone and emotional context right. TTS from Google and Samsung running locally on a phone is already listenable so I don't think minorly better AI is going to eat the audiobook market if it hasn't already.

It’s possible that doesn’t matter to most people, and the art world will have to realise that mass-produced schlock is all the public really wants. We’ll see.
It's like saying: for hammering, a hammer is better than my pinky finger.
That's kind of the point of tools.
Do you assume it will stay the way it is?
