A human brain is just the summation of all the content it’s ever witnessed, though, both paid and unpaid. There’s no such thing as artwork that is completely 100% original, everything is inspired by something else we’re already familiar with. Otherwise viewers of the art would just interpret it as random noise. There has to be some amount of familiarity for a viewer to identify with it.
So if someone builds an atom-perfect artificial brain from scratch, sticks it in a body, and shows it around the world, should we expect the creator to pay licensing fees to the owners of everything it looks at?
