You're basically arguing a techno-religious Pascal's Wager, so my contra-argument is the same: if the nonzero probability is a 0.1% chance, would you really risk your one and only life dedicated to something that has a 99.9% chance of not happening, whether it be real or techno-heaven?
You're implicitly assuming that accepting the Wager means "losing" your one and only life. OK, it depends on your utility function, but most religious and techno Wagers don't require immediate martyrdom.
