Reply #17: I think it goes back to what makes you, you

I don't even know what a psyche is, what it is made of, what it encompasses.

If it's simply a certain "pattern" then maybe I suppose uploading would one day work. But we know now that our brains are different not just at the microscopic level or the macroscopic level but at the quantum level. I don't know how you replicate that.

I have pretty high doubts that life extension that keeps you, you, involves anything other than an intact or mostly intact brain.
Not impossible, but close. Then again, am I a "different" me than I was 20 years ago? I don't think so, but the almost 41 year old me thinks and acts quite differently than the almost 21 year old me did.
