How does large scale randomness result in such complicated and intelligent systems, while after decades of research and all the computing power we have today, we still struggle to model and reproduce the intelligence of an insect.
I feel as though it's simply Occam's Razor to assume that evolutionary complexity is the result of randomness because I know of no better explanation. Is there a self-reinforcing process at play? (Natural selection partially counts as reinforcing, I just feel like randomness is still the engine that powers it).
