The problem is, until we are post-scarcity or post-money (I don't know what that word is), then the incentives are there to abuse a system of brain/computer interface and uploaded consciousness. That being said, I don't believe we can ever really get to post-scarcity or post-money (again, what's the word?) without those two things being integral.

Removing the 'negative' from a person's life and allowing them to exist perpetually is, I believe, required to avoid the current selfish race to the bottom of hoarding resources and capital.
