For anyone interested, the video below is long and full of filler but seems to give a plausible overview of AI and singers.

A plausible theory of future songwriting is that millions of people who can't write, play an instrument or sing will rattle song ideas (parameters) into AI programs and generate billions of songs that will compete for attention and glory. It won't matter that there will be no humans involved in the actual execution of the song...just whether a song is appealing on some level or not.

Fd, I know that you contend that humans can never go away in this process. But I question that. Or one human in one place being recreated as a hologram surrogate in 100 others.

Time will tell.
