Query: Druggies suck as "futurists"

I grew up reading the prophecies of these acid-tripping "futurists" like Robert Anton Wilson, Timothy Leary, F.M. Esfandiary et al., about we'd become "physically immortal" by now. How has that "immortality" worked out for these guys lately? Enough of this nonsense. They belong in the neighborhood of kooks like Hal Lindsey and Harold Camping.
