Science fiction has traditionally been economically naive, with a strong libertarian streak, which I think is like a crude Leninism. That's attractive because it could be used to explain everything, and if only we lived by its tenets, everything would be perfect.

Science fiction was rocket-mad for about 40 years until aerospace hit a brick wall about 1970. I would not write off space colonisation or exploration completely, but we are profoundly ill adapted for going boldly into outer space.

Having a Congress with a more diverse educational and professional background would serve the country well. And given the budget challenges facing America today, we might benefit from a few more cold, calculating problem solvers, and fewer courtroom impresarios.
