In fact, I see nothing in this whole thread that goes beyond ad hominem. Please provide arguments for or against the one on-topic notion for this story: "Ray Kurzweil predicts the cloud will ... help expand our brain capacity beyond its current limits."
This, to me, is a very sensible, even self-evident, statement. Right now I use Google's cloud of computer mapping services to navigate virtually anywhere I go. I use Google's cloud of search services to find the answer to virtually any question I may have, from the syntax for an API, to repairs for my car, to the lyrics to some song I like. Even in the last few years these capabilities have improved dramatically; I'm sure they will continue to do so.
You may not like the word "cloud", but it accurately describes computing systems with multiple redundant computers accessing multiple copies of information to provide speed and reliability.
Frankly, all the spastic reactions whenever Kurzweil's name is used make you guys look like the unbalanced ones, not him.
(Note that while I'm replying to the grandparent of this conversation, this is directed to the thread as a whole. This one comment is innocuous; the trend here is not.)
