The human brain is not magic, neither is that of chimpanzees, rats, dolphins or gorillas - but they are all the results of billion years of darwinian evolution in a competitive environment. However advanced our AIs will become, they'll never be anything like a mammal brain.

I'm sure we'll be able to develop computers that are better than us at solving increasingly general problems, but that is nothing like having a human-like brain, only much smarter and able to improve itself. It will still be a problem-solving machine.

Natural wings are also the result of a billion years of Darwinian evolution, and people's efforts to engineer imitations of them failed laughably until someone figured out the principles upon which they worked. Once that happened, human intelligence was very quickly able to engineer machines that produced far, far more lift than the designs nature had been tinkering with.
