When you think about what Homo sapiens are about, you almost feel that we are replacing ourselves. We won't be able to breathe and breed on this earth, so we replace ourselves with androids that can do. The androids can go up into space and take the future of humanity forward because maybe we just bow out with a carbon-based epoch.

Underpinning them was the belief that the grim reality of impending death can be talked away by trying to invest in the present reality of life. I didn’t believe that at the time, but now I do. By definition, you have to live until you die. Better to make that life as complete and enjoyable an experience as possible, in case death is shite, which I suspect it will be.
