We do already! Hah! You've got no way to disprove it!
Yeah, pretty much that. Eh, why not, as a nihilist it doesn't really matter.
You could just integrate your personality (which you might not even have) into a practically eternal computer and exist as data only and just keep running the same program that gave you unlimited processing power and, well, generic omnipotence and stuff.
But then again, if you get that deep into science fiction, you yourself don't have much in terms of consciousness or free will. All you are is simply programmed over time and is based on some basic chemistry... and if you "transcend" your body to simply become data, none of that will be needed, so the illusion of individuality and, you know, just "being you" would simply fade and what's going to be left over - fuck I don't know, but I'd wager it'd be pretty passive because it would have no ambition that generally is founded within the instinct to survive and pass on your genes... So in a way, you'd become your own apathetic god, existing in your personal universe (brain in a jar an' stuff, if you know what I mean) and absolutely omnipotent, but without any drive to do anything because there'd be no point in doing so.
"Being human" involves having illusions about importance and meaning. Once you get passed that, there's nothing.
