Sure, some people are not critical thinkers. I am not a worshipper of Kurzweil and not into Transhumanism, but I liked the historical charts he drew showing exponential acceleration over a wide time interval and tech domains. I feel his evidence of historical exponential progress was compelling, but what u do with that evidence is up to you. If you have something to say about that point I am happy to hear it, but you mostly seem to be lashing out at 'silicon valley' types which is a mischaracterization of who you are talking to. I respect Kurzweil because he is a real engineer, entrepreneur and a helper of those less fortunate (the blind in-particular).
