“Evolution optimizes strongly for energy efficiency because of limited food supply, not for ease of construction or understanding by human engineers. My wife, Meia, likes to point out that the aviation industry didn’t start with mechanical birds. Indeed, when we finally figured out how to build mechanical birds in 2011,1 more than a century after the Wright brothers’ first flight, the aviation industry showed no interest in switching to wing-flapping mechanical-bird travel, even though it’s more energy efficient—because our simpler earlier solution is better suited to our travel needs. In the same way, I suspect that there are simpler ways to build human-level thinking machines than the solution evolution came up with, and even if we one day manage to replicate or upload brains, we’ll end up discovering one of those simpler solutions first. It will probably draw more than the twelve watts of power that your brain uses, but its engineers won’t be as obsessed about energy efficiency as evolution was—and soon enough, they’ll be able to use their intelligent machines to design more energy-efficient ones.”
