Just watched it last night. I, too, was guilty of thinking too linearly about the future, when the exponential model for technological advancement makes a lot of sense (and has been backed up by empirical data). State of the art tech is used to make the next generation state of the art tech, and so on. Makes me excited to see what's next.
It will be interesting to see if technology can advance fast enough to deal with global warming and population growth. We'll see in the next thirty years, I guess.
