A human brain is three pounds of the most complex material in the universe. It is the mission control centre that drives the operation of your life, gathering dispatches through small portals in the armoured bunker of the skull. This pink, alien computational material, which has the consistency of jelly and is composed of miniaturised, self-configuring parts, vastly outstrips anything we’ve dreamt of building.
Using those brains, humans have done something unique. As far as we know, we’re the only system on the planet so complex that we’ve thrown ourselves headlong into the game of deciphering our own programming language. Imagine that your desktop computer began to control its own peripheral devices, removed its own cover and pointed its webcam at its own circuitry. That’s us.
