A good line, but still doesn't justify the level of certainty which many of these people have in future events turning out the way they think they will.
Back in the 90s, as a callow teenager, I happened to be lurking on a mailing list for transhumanists. One day someone on the list, well known to many of the others, died. "Fortunately", as the announcement to the list said, "his body was cryogenically frozen, so we'll all see him again after the singularity!" This was followed by a bunch of posts expressing confidence that this would indeed happen.
It was roughly at this point that I decided that these people may be somewhat disconnected from reality, and living in a fantasyland of what they'd like to be true -- while I admit it's possible that this guy will one day be revived, there's no goddamn reason to have any confidence in it happening.
