Interesting question indeed.
Back in the 60’s a group of studio musicians who were eventually referred to as “the wrecking crew” provided the early musical background for The Byrds, The Beach Boys, The Doors (?), and who knows who else.
Audiences who saw those groups had no reason to believe the musicians onstage didn’t record those songs that they loved. Does that classify as deception?
An 80’s band whose album I really liked usually played with a drummer I admired and respected. However, I read a few years ago they used a drum machine when recording the album. I was seriously conflicted as to whether I still liked the music as much knowing that bit of information (I saw them touring the album with the aforementioned human drummer).
In my mind there are parallels between AI and these pre-AI occurrences.
Guessing that only humans can create something truly “new and unique” makes me inclined to dismiss AI as a viable, long-term listening option.
