My mind uploaded to a computer would just not be me, it would be a copy of me. My mind is an emergent property of my brain, it's not something tangible that can be transferred.
And once that copy of my mind is uploaded to a computer, then what? Eternal virtual reality? Robotic body? Disembodied consciousness? What if some sociopathic 12-year-old gets a pirated copy of your mind on his computer and decides to torture it?
