“I’ll take the Marylin Monroe look-alike.”
So a computer can come up with a Marilyn Monroe - big deal; when AI comes up with Marilyn Manson, then I’ll be impressed - computer programs can imitate the ordinary, it takes people to come up with the truly weird.
I could see them being used to recreate concert experiences, imagine being able to see a reasonable facsimile of a Beatles concert, with figures that look and move just like the real thing.
