Imagine a 6 year old boy sitting in a box on the sidewalk. He is wearing a helmet and goggles, and going “Vroom, vroom.” Fast forward 6 more years. The boy is now in his treehouse repelling alien invaders.
Fast forward again for one third century. The boy now has a very, very fancy treehouse. He sits in it for hours playing with the controls and going “Vroom, vroom.” I envy him.
