I read Ray Kurzweil's book over the Summer and, despite the charts and graphs, I don't buy the wholesale change in human nature that he insists is coming in the next several decades. Sure, there will be scientific breakthroughs and sure, technology will see exponential surges. But how he gets from there to a global utopian vision I don't get. It's the people part that he misses. People always screw things up.

Not only that, according to Derek Lowe, Kurzweil also misses the mark on biological science.
