What really matters is the society where we want to live in. It doesn't matter much what kind of technology allows private entities to reproduce creativity. We can assume these brains are not virtual and are actually organic and more capable than human ones, or that they are magical black boxes.

Since it changes incentives and mechanics of the creativity market so much it forces us to reassess current approaches. I can't agree that mechanism behind this tech and the approach to IP is of any consequence. We don't make laws, norms and judgements for the sake of our tools.

It's ok to say that we're not ready to arrange things in a proper way yet, without letting everything slide on some arbitrary technicality.
