Q: what do you think separates humans from other species?
A: opposable thumbs, walking on 2 feet, large brain, and good talking skills. that's what got us started, and then after a few thousand years of thinking, we started to invent things.
and after a few thousand more years we started to invent more things and it has started to get really crazy really fast. that's pretty much how it happened.
and it's not over yet, pretty soon the things we've invented will start inventing things
