The author (as so many do) admits to using AI in marketing efforts - where's the empathy for copywriters?

I sympathize to a point. No one's copyrighted work should ever have been allowed in the training sets used in for-profit tools development without consent and monetary compensation. However, I have very little sympathy for creators in any art form who can't stand up with equal vehemence for those working in other branches of the arts.

Aside from the theft of work to create a product, AI should be held to the same standards of copyright, when it comes to the output of the tool, as any human author. And the burden of proof should fall on the tool-maker, not the end user, to demonstrate its innocence.
