Honestly, I think you're barking up the wrong tree here. Even his strongest critics generally concede that he's a brilliant man who has contributed significantly to technology.
Please understand, I'm not a Kurzweil fan boy. I do think a lot of his conclusions are inevitable in the long term - say 100 years out - but I'd guess it's 50/50 whether or not his timelines are too optimistic to benefit any of us here personally.
What I'm reacting strongly to here is the knee-jerk dismissal of his credentials and accomplishments by some on HN due to their incredulity towards his later ideas. It doesn't encourage an informed debate, and quite frankly smacks of a religious or political argument - which admittedly many of his supporters are just as guilty of.
