re: Tools vs Humans
I have a very different view of the world than you have. Insults aside I understand part of your logic and have no problem with big goals or wanting humans in large masses in space. I just don't think your route is the way.
If a cheaper method to LEO doesn't come along and if an impactor or some shortage reduces our abilities here I think we will sink into another dark ages for those very reasons you seem to think the Internet or robotics are the best solution to a problem.
