That's a different goalpost. I get the difference between 8 billion brains, and 8 billion instances of the same AI. That has nothing to do with whether there is a difference in copyright infringement, though.
If you want another goalpost, that IMHO is more interesting: let's discuss the difference between 8 billion brains with up to 100 years life experience each, vs. just a million copies of an AI with the experience of all human knowledge each.
(That's still not really what's happening, which is tending more towards several billion copies of AIs with vast slices of human knowledge each).
