We are truly stupid if we turn backwards right when we figure out how to do high efficiency fusion, store energy as extra mass, and other off the wall things we've cooked up in sci-fi but haven't gotten around to figuring out in the basic physics departments.
That quote is simply stunning. Clearly, us as a people and civilization is retarded if we are so dumb as to let "science" be the limiting step in progress and not just the imaginations of our sci-fi writers.
Not that much of the rest of the post isn't worth considering, but that statement surely needed comment. Clearly we're not even CLOSE to figuring out how to do all those things.
