• A comparison between edge and motion detectors in the human retina with similarly functioning computer vision programs suggests that the retina does the job of 1,000 MIPS (million of instructions per second) of computing. The whole brain is 100,000 times larger than the retina, so is worth perhaps 100 million MIPS of efficient computation.
• Information handling capacity in computers has been growing about ten million times faster than it did in nervous systems during our evolution. The power doubled every two years in the 1950s, 1960s and 1970s, doubled every 18 months in the 1980s (Moore's Law), and is now doubling each year.
