Different versions of immortality or of an “afterlife”

Check out this article and different versions of what could be an afterlife or way to experience immortality, so to speak . If any of these ideas r even plausible , ever , at any point in human history… they all sound scary to me and if that’s the only version of an afterlife that’s possible (the kinds described in article)…. No thanks!!

Oh dear. Anything involving Ray Kurzweil immediately and automatically triggers the "Oh no, not again" response and I close the page. Just another version of the perennial "Singularity is almost here" claim that is constantly getting pushed out another 5 or 10 years. He's getting old enough to be worried that he will probably miss it.

As for me - also ... No thanks!!

The research into biological processes could be interesting in terms of possible greater understanding of how to remain healthy as we age. But extending human lifetimes in itself doesn't seem so important to me.

The ideas about computer technology are simply unsubstantiated - there is nothing to suggest that there will be any transfer of anything 'living' taking place. A person's life ends. A machine technology is switched on. But there is no experimental evidence to support the idea that the machine could thereby (a) become alive and (b) be an actual continuation of a specific human. It is one of the most crackpot ideas I've heard.

Even if it was theoretically possible to make a 100% replication of your brain it would result in a new person who is like you but whose conscious experience you don’t have access to.

If we ever could invent immortality of this kind, we would also have to make everybody infertile!
