I don't mean to pick on you (and I certainly didn't downvote you), but you seem like a posterboy for just how easy it is to take inventions and innovation for granted after the fact.
I find it instructive to occassionally go to Youtube and load up commericals for Windows 95, 3.1, the first Mac, etc., or even to dust off and boot up an old computer I haven't touched for decades. Not to get too pretentious, but it's a bit like Proust writing about memories of his childhood coming flooding back to him just from the smell of a cake he ate as a child.
When you really make a concerted effort to remember just how primitive previous generations of computing were, I think it puts Kurzweil's predictions and accomplishments in a much more impressive context.
This was the state of the art PC back when Ray was forming his first companies: https://www.youtube.com/watch?v=vAhp_LzvSWk
I posted some other thoughts about Ray's track record awhile back:
==========================================
I read his predictions for 2009 only a couple of years before they were supposed to come about (which he wrote in the late 90s), and many seemed kind of far fetched - and then all of a sudden the iPhone, iPad, Google self-driving car, Siri, Google Glass, and Watson come out, and he's pretty much batting a thousand.
Some of those predictions were a year or two late, in 2010 or 2011, but do a couple of years really matter in the grand scheme of things?
Predicting that self-driving cars would occur in ten years in the late 90s is pretty extraordinary, especially if you go to youtube and load up a commercial for Windows 98 and get a flashback of how primitive the tech environment actually was back then.
Kurzweil seems to always get technological capabilities right. Where he sometimes falls flat is in technological adoption - how actual consumers are willing to interact with technology, especially where bureaucracies are involved- see his predictions on the adoption of elearning in the classroom, or using speech recognition as an interface in an office environment.
Even if a few of his more outlandish predictions like immortality are a few decades - or even generations - off, I think the road map of technological progress he outlines seems pretty inevitable, yet still awe inspiring.
