This is a super interesting analogy and it's changed my perspective a bit. But it all depends on your end goal. You say:

What is it doing? Do we want our AIs to maximize learning or just human-like behavior? If it's the latter, I believe you absolutely want to look at neuroscience and emulate the human brain. Of course, airplanes are super good at flying, but they look nothing like birds.
