I wonder just how possible it will be to have a 100% artificial body. Would we just be able to upload our consciousness then destroy our biological brains, or would will still need to keep a little bit of it?
I don't think it will be possible to get rid of the brain for centuries to come, at the least. The only way I could think of preserving the consciousness and getting rid of the biological brain would be to map out the individual's brain and basically copy it in every detail to an artificial brain. Every synaptic connection, every cell, everything. That's some serious science.
