I'm very wary of the whole mind uploading shtick because we don't really understand what the mind is... how can you be sure that the "you" stored on the chip is actually "you" and not just a copy?

The copy would have all your memories and personality traits and swear blind it is you but still... how could you be sure?

I mean, the copy wouldn't care, it gets to live on... but the you that sits in front of the computer reading this now, is that really transferred?

It's like that episode of Star Trek where some dude reckons the transporter actually kills you and just spits out a perfect copy with all memories intact at the other end.

Heck there's a convincing argument that every time you enter deep fully unconscious sleep this happens.

When you wake up your brain assembles another "you" from all the stored memories and programmed habits physically held in neurons and whatnot but it's not the same "you" that went to sleep the night before... That "consciousness" was obliterated when you became "unconscious".

You're nothing but an endless series of copies created every morning and the very first original you "died" the first time you ever went to sleep after gaining consciousness... you never even made it out of the womb lol.
