Post-Humans don't want to live forever. They are capable of detatching themselves from their egos and accepting death.

This kurzweil guy is rocking the same fear of death vibe (a prehuman drive for survival) that keep most traditionally relgious people from experiencing the actual spiritual evolution that the real post humans will go through. Kurzweil is just basing his mythology to suppress the fear of death on tech and sci fi themes rather then Christian myths.
