Thomas Barnett is getting bombarded with the more evidence crowd:
I'm still not convinced! Have you taken into account inflation and the Hubbert's Curve effect on crude oil prices in your calculations? Because if you could just get those numbers right, I'm pretty sure I'd be emotionally invested in your vision of the future! No, really! Just get me those two numbers!
So who could drop launch costs that much? These guys are predicting launch in 2018, 13 years from now, of a structure that could do exactly that, a space elevator.
The question is what are the numeric border conditions that would knock your predicted future into nonviability? How likely are we to get to those numeric conditions? In Dr. Barnett's case, I think we're talking about pretty wide variances and pretty unlikely outcomes. But then again, you never know.
Until 1991, space elevators were creatures of science fiction and engineers calculated that only mythical "unobtanium" could build the things. One scientist in Japan finds Single Walled Carbon NanoTubes (SWCNT) and we're off to the races with lots of previous eminently sensible predictions becoming very unrealistic in the blink of an eye. Disruptive, transformative innovation is becoming more common so predictions without border conditions are becoming less valuable, especially long term predictions.
