My professional artist friend said the same thing. I don't think anyone could define the term if they wanted to. I see enormous beauty and great "imagination" in what DALLE-2 is producing, e.g.:

"Oil painting of a sad girl looking out the window of a school bus" https://twitter.com/jennifermarsman/status/15175974527649546...

“avocados dancing, drinking, singing and partying at a Hawaiian luau” https://twitter.com/TheRealAdamG/status/1517906900540657665

Can anyone verbalize what these images might lack, or might gain through "soul"? Objective answers only please.
