Do you remember the opening scene of Stanley Kubrick’s “2001: A Space Odyssey”? The director starts a movie about space by first showing us early humanity. We are introduced to two warring factions of hairy proto-humans, yelling and grunting at one another over some unknown conflict. That night one of the tribes wakes up at sunrise to a strange, black, rectangular object. In the shadow of this monolith, one of the members of the tribe picks up a bone and examines it. After a moment, it begins to beat the ground with this first “tool.”
