When you are out in public, you don't have an expectation of privacy. People can see you, they can take photos of you. The worker at the cafe will probably remember you and your order. This is fine. But when tech does the exact same thing but with scale where everywhere you go, everything you buy, etc is tracked and analyzed, it's now questionably immoral despite legally being fine.
That's how generative AI is to me. Its doing something people have been doing themselves forever, but now it's doing it faster and easier than ever before which changes the equation. The arguments of "its not real creativity" are a coping mechanism. We are upset that something that was previously quite unobtainable behind years of learning and hours of effort is now trivially accessible to anyone with a computer.
