Your brain isn't magic, you learn from experience.

AI isn't magic, it learns from experience.

If the inputs used to train an AI are "stealing", why aren't the inputs (experiences, what you read, what you listen to) to your brain?

And I don't mean in the reductive sense of "you are a human and the AI is not" I mean the act and the process and the result are the same, what differs is the substrate and the architecture — proton exchange across lipid layers vs. electron flow across doped semiconductors for the former, and transformers vs. the evolved chemical mess of the human brain for the latter.

If AI training company needs to train only on materials that they paid for the copyright of and never on materials that are just publicly available on the Internet then a person should have the same obligation. What you read influences what you create. If AI company trained on publicly available texts that it didn't pay for can't publish AI creations then a person who trained themselves on information they haven't paid for a license to shouldn't be allowed to publish anything either.
