Religion for techies. Apocolyptic millenarian beliefs (Singularity)? Check. Transcendence and life after death? Check. Belief in purity and rituals (Vitamins and workout routines)? Check. Hold a service at the TED Talk, etc. . . . It might not be the same literal thing as a religion but transhumanist culture sure seems to be serving the same basic human needs.
Yep. Kurzweil has been banging this drum for a long time. I read Spiritual Machines a long time ago and found it to be a simple rehash of 90s-Extropian tropes - utility fog, uploads, all the goodies needed to glue science-fiction nerdbait to a thin rehash of Christian rebirth millenarianism. The book went away in one of my periodic purges, or I'd check to see if he changed his dates.
2009 "Artificial voices sound fully human" seems a bit optimistic.
as does 2019 "Household robots are ubiquitous and reliable."
