Take the evolutionaries. Led by the University of Michigan's John Holland until his death in August 2015, they believe that evolution, not the brain, is the master algorithm.

The algorithm involves a hierarchy of classes, parts of physical objects, and subroutines. The loops of these graphs are eliminated by replacing each by a single “equivalence class” node.

Perhaps soon enough, we'll figure out that master algorithm and understand our brains better. Then we'll either be able to make better AI — or AI that's better than us. It's worth finding out.
