The human brain seems to be the most complex structure in the known universe for its size (Figure 6.1). It has more nerves than there are people in the world (or devices on the Internet), but it took hundreds of millions years to evolve.

The brain of a bee is just a sliver of neurons, but it lets them fly, form colonies, and communicate with each other better than any robot of that size. Yet nature didn’t stop there because our brains came from brains like theirs, so what is difference between evolving a brain and building a computer?
