Look at the picture above. It is the motherboard (the main printed circuit board) from a computer. How do you think it came to be? It could have been formed by an earthquake at a spare electronics warehouse. After all, it’s at least possible that in the midst of the warehouse shaking and being destroyed, lots of spare electronic parts started crashing into each other and, as a result, just happened to produce what you see above. Of course, I hope that no one is silly enough to believe such a story. It is obvious that the motherboard is the result of careful design and craftsmanship.
As someone who started programming computers with punch cards, used DOE grant money to buy a 40-Megabyte hard disc for $1,200 in 1989, and stored his unimaginably vast (800 Megabytes) thesis experiment data on sixteen separate 10.5-inch magnetic tape reels, I have witnessed a lot of progress in the area of computers. I marvel at how technology can produce a hand-held device that is more powerful than the VAX-11/750 (pictured on the left, without the keyboard and monitor) that I used to analyze my thesis experiment. Nevertheless, with all of the amazing progress that human engineering has produced, it doesn’t come close to what we see in the natural world.
Consider, for example, this article’s comparison of a personal computer to a mouse brain:
A personal computer simulates a mouse-scale cortex model (2.5×106 neurons) 9000 times slower than a real mouse brain operates, while using 40,000 times more power (400 W versus 10 mW). [reference marks omitted for clarity]
