I just actually thought that many of the great artists absolutely did paint, sculpt, or draw their creations "by hand", themselves. I suppose they used tools: the brush, chisel, pencil. Not sure how comparable those are to having an LLM write code for you.
The reality is that many if not most of the big names had apprentices who did a lot of the actual work. Art historians spend a lot of time arguing about whether a given Leonardo was really a product of Leonardo's hand, for example.

The artist I was primarily thinking of when I wrote that comment was Chihuly, whose workshop is famously more like a factory than a studio.
