Please don't take this to be dismissive of your comment, because that's not my intention, but...

I think people like Ray Kurzweil are essentially religious. Instead of a messiah and heaven, they think of salvation in terms of a singularity, immortality, or a way of ascension. It feels very religious to me, and as such, detached from reality and physical possibilities.

Yeah. He makes a good case for the computer side of upload being possible--and totally skips over the biological side, assuming it will be available on the same time frame.

Even if upload does not produce a singularity or the like it still is a huge step towards getting more time to address other issues and it makes interstellar solutions viable. But when we can read out the human mind remains an unknown.
