Ray Kurzweil's latest book about all this 'The Singularity is Near', was released in 2005. It has some compelling arguments is definitely worth a read if you are interesting in the longer term implications of computer technology and networking. He hasn't said all that much new in the years since then and this article doesn't really contain any new information.
Doesn't think what? That the Kurzweil book is an interesting read? I think what you are trying to say is that this guy doesn't agree with the notion of the singularity. Fair enough. Though I think his assertion that we aren't in a time of accelerating change is a minority view amongst recognized futurists.
But when comparing the cultures of humans and chimpanzees, that's where the real differences are visible. "That's the promise of what humans are. It's not the individual intelligence but this collective intelligent culture," he said.
