I don't know if this is a relevant data point, but I was raised in an atheist communist family, and I still like the idea that people could live forever (or at least much longer than today) and I think the world could be significantly improved.
It seems to me one doesn't need a religious background for this, only to overcome some learned helplessness and status-quo fatalism. Okay, the religion (and also communism) already provide you a story of a radical change in the future, so they kinda open the door... but I think that living in the 20th/21st century and watching the world around you change dramatically should allow one to extrapolate even if they wouldn't hear such ideas before.
I'm giving a talk to the Boulder Future Salon in Boulder, Colorado in a few weeks on the Intelligence Explosion hypothesis. I've given it once before in Korea but I think the crowd I'm addressing will be more savvy than the last one (many of them have met Eliezer personally). It could end up being important, so I was wondering if anyone considers themselves especially capable of playing Devil's Advocate so I could shape up a bit before my talk? I'd like there to be no real surprises.
I'd be up for just messaging back and forth or skyping, whatever is convenient.
