yeah because of blind faith in 'technology'.
There is a lot of blind faith in tech, a lot of hand waving about hard problems from ostensibly "smart" people. Ray Kurzweil, who is 71, thinks he will live forever - he predicts by 2029 medical tech will be at a point where each year will add at least another year to your life span, effective immortality. He also thinks anthropic climate change (yeah, I know Juan thinks it's all a big hoax, though I'm not clear who benefits from such a hoax - massive vested interests in carbon fuel industries drive troves of billionaires, not to mention entire nation states, but in any case) is nothing to worry about - Moore's law applied to renewables, it's no fucking problem :). It all sounds like technology as religious experience to me. Even if you buy into the inevitability of this future tech, is it really a road map for utopia? Humanity is facing some tough shit, much of it directly tied to tech progression: massive surveillance states on levels never previously imagined, wealth continually centralized among a tiny world elite, existential risks as a direct result of technological advances - atomic weapons, other "WMD", and of course turning the heat up on the planet by dumping carbon into the atmosphere at ever greater rates. It seems like we are on a race to destroy ourselves... Will tech help us or hinder us? Imagine the "democratization of high-tech" that comes with all this progress - what happens when anybody with the latest & greatest 3d printer and a few other relatively cheap odds and ends can create an atomic bomb? What happens when gene hacking becomes truly cheap and ubiquitous, and anyone with a little biology knowledge and the right hardware can engineer a plague? What's the answer to the Fermi paradox?
