In an interview with Gizmodo, artificial intelligence expert Ray Kurzweil says we're very close to reverse-engineering the human brain, and that the design of the brain lies in the genome. According to Gizmodo, Kurzweil says that the three billion base pairs of the human genome can be compressed down to about 50 million bytes and that half of that information deals with the brain. Those 25 million bytes would be about a million lines of code.
