Then you become a cyborg and "evolve" by upgrading. Sounds pretty sweet to me. Probably the easiest route to "immortality" too.
It opens up for a boatload of problems, though. Like the clone problem. Communism likely has to be achieved and property abolished before this is feasible. Otherwise, let's say you upgrade, but leave your old self active. Who owns your assets? And who speaks for "you"? And if killing the old body is the law, when, legally, does you-2.0 become a person? What if the transfer takes place over relativistic distances?
We sure have to change a lot from being greedy self-worshiping apes before this stands a chance.
I don't think it will - human nature being what it is, I think machine hosted humans can be no more than slaves, serving those who can and will exploit being able to possess and inherit.
Time will tell, and I won't be around, as I'm content with having an unpredictably short life span.
