Uploading Your Consciousness into a Computer: Alt-you

OK, so if it could be done, the problem would be that there would be 2 "yous."  The original -- you sitting there with all your memories and thoughts hooked up to some kind of brain-copy machine.  And then there would be Alt-you, on the computer.  Assuming you could copy but not just cut & paste.

So, as you sit there, the Alt-you could, for all intents and purposes, act and think as you do/would, and if it were then in a robot or somehow then reprogrammed into the Alt-you human brain, two people, you and him.

So, the one made immortal at that point would be the other one, and you'd be sitting here in with your individual unique consciousness, still watching this other person/entity, who may be very much like you, but is not you, because you're still there, in your head.  And you'd be seriously jealous, because as you continue to deteriorate and die, he/she'd be out there living their new and continued life!  They could even do your job and be the parent of your children and the excellent spouse you are to your life partner!  And you'd again, be watching as the outside person.  You'd have the peace of mind, I guess, that Alt-you would be the same as you to everyone else in the world, and could continue being you to everybody.  But again, it's the other you, and there's no way to get this current you outside your head and into any other consciousness, is there?  As intimately as you are connected to your own neurons, those are the ones that make  you feel like you with your own memories and consciousness.  And you'd still die, just like you would have had you not uploaded yourself into Alt-you.

And the new you that you had thought you would become would be Alt-you's (Alt-yours?).  To the world, you could almost be considered to become immortalized, but to you, yourself, sayonara!

But, brain transplant -- taking your brain and putting it into some healthy new body or fully hooked-up, robotic brain-vessel.  I suppose that's the better route, right?  Because then, it's still be the original you in there.  That'd be good.  Until you were finally ready to let go and surrender.
