If prompting some AI to create music is making music, those retired seniors watching construction work are building infrastructure.

Retired people by definition are not working, but that aside...

Are you saying that programmers don't create software because they just "prompt a compiler"? Are you saying authors don't write books because they type into a word processor? Are you saying illustrators and artists don't draw because they are using a tablet? Are you saying construction workers aren't constructing because they're using excavators and cranes?

I appreciate that many people suffer from AI Derangement Syndrome, but it's a ridiculous notion. "AI" is a tool like any other tool.
