If your subjects are eternal... they'll survive.
I don't believe in personal immortality; the only way I expect to have some version of such a thing is through my books.
I don't think immortality is necessarily the key to understanding the world. You have to be careful with what you think you're achieving. I'm all for science discovering amazing and fantastic things about our world, but I think the motivations behind it are slightly askew.

Immortality is a by-product of good work.
