If you want to make this argument, then AI companies should be required to treat their AI models like employees. Paid for 40 hours a week of work, extra for overtime.

This is like asking someone to prove God doesn’t exist. The burden of proof is on you to show how humans are effectively over hyped plagiarists. You’re the one making the claim.
