I've been researching Aubrey de Grey, Ray Kurzweil, Peter Thiel, Ellison, Brin, etc. and other people who are researching or supporting life extension. It seems that there are a lot of smart people who believe that we'll be able to realistically extend our lives to 120+ years. That will then be enough, for some of us, to survive until the point where technology allows us to extend our lives indefinitely.
But the first generation of immortals will need lots of money. Read more here:

Newsflash: It's impossible to experience nothingness, therefore you can only ever experience somethingness, therefore you are eternal.
No, that doesn't equal you being eternal. It equals your experience being limited to when you are alive which is why people are trying to extend their lives.... So they can have more experiences and maybe switch a career after they've spent a natural lifetime mastering one, or maybe experience what it's like to be young again or be rich or live long enough to travel off this crappy rock that encourages the eat or be eaten lifestyle, which is why i want my investments to succeed and i can enjoy my space yacht with my hot android GFs. (see how i got that back on topic )
Perhaps you're looking at the situation too dogmatically. Deckard would surely confirm that memories (and reality) is something of a slippery fish. Impossible to confirm, absolutely.
But if it's impossible to experience nothingness, then it's impossible up experience nothingness.
Somethingness prevails.
Perhaps your're being chimerical.
You need a brain ATM to experience something in your current human form, therefore if that dies, so do all your human experiences. I'm sure the dead atoms that fall off your body on a daily basis have some sort of experience, but that's not the experience I want to extend to if that's eternal life.
