Copying a style isn’t theft, full stop. You can’t copyright style. As an individual, you wouldn’t be liable for producing a work of art that is similar in style to someone else’s, and there is an enormous number of artists today whose livelihood would be in jeopardy if that was the case.

Concerns about the livelihood of artists or the accumulation of wealth by large tech megacorporations are valid but aren’t rooted in AI. They are rooted in capitalism. Fighting against AI as a technology is foolish. It won’t work, and even if you had a magic wand to make it disappear, the underlying problem remains.
