Yes, but we're forgetting two advances that the world did not see 40 or even 10 years ago. Huge huge advances in nanotechnology and the internet, neither alive back in the 60's and 70's boom. I guess some could argue the internet was technically "invented" in the 70's although it was nothing even close to what it is now or in the late 90's.

We already have tomorrow's technology, we're just still learning it, figuring it out, and perfecting it. They say by the year 2012 that human knowledge will double every year due to huge advancements in science and biomedical.
