Artistic expression does not « move on » without me, or people.
Artistic expression is people in motion, alone or in groups.
You’re talking about the economics of performances and artefacts, which are _something else_ out of artistic expression.
EDIT to clarify/reinforce:
Elvis without Elvis isn’t Elvis. Discs, movies, books are captures of Elvis. Not the same thing.
Miyazaki without Miyazaki isn’t Miyazaki. It may look like it, but it is not it.
Artistic expression is someone’s expression, practice (yours, mine, theirs). It’s the definition of the originality of it (who it comes from, who it is actually made by).
A machine, a software may produce (raw) materials for artistic expression, whatever it is, but it is not artistic expression by itself.
Bowie using the Verbasizer is using a tool for artistic expression. The Verbasizer output isn’t art by itself. Bowie made Bowie stuff.
What would be gatekeeping is if someone prevented you to pick a pencil, paper, a guitar, a brush, to make something out of your own.
You’re the only one gatekeeping yourself here.
Looks like it’s the same pattern as with blockchains, and NFTs and Web3 stuff and the move fast/break things mantra: you cannot argue for and demonstrate for what your « solutions » actually solve, so you need brute force to break things and impose them.
