the difference between bird wings and plane wings is that evolution cannot evolve materials and designs that are in principle unevolvable such as plane wings and engines. When it comes to the brain, you could say that nature cannot evolve fiber optics or silicon circuitry, but the reality is that what it has is extremely constrained and what is evolving is algorithms that work within extreme constraints. It remains to be seen that similar constraints to the material constraints apply to the limitations of evolution regards algorithms. Because if similar limits don't apply the algorithms might very well be theoretically optimal like honeycomb shapes and atp are.
