I'm not saying we should settle for anything. Certainly not.

But to forget the awesomeness that already exists is a mistake with consequences. When looking at the big picture, it's important to realize that our current tradjectory is upwards. When planning for something like space travel, it's important to remember that air travel sounded just as crazy a hundred years ago. And when thinking about thinking, it's worth remembering that this same effect will hit whatever awesome thing we think of next.
