Good point. I would compare it with human speech. Human speech is a powerful mean to communicate and for this reason it is thus very tempting to develop artificial systems that can communicate in the same way. But human language is far from optimal. In the same way, I believe that human brain is powerful but far from optimal.

The strength of human brain is its ability to adapt to fast changing context. The solution (function) it finds is however usually far from optimal.

I also think that the future of computing is the development of systems that can efficiently adapt their rules of actions according to execution context evolution. The programmers of today will then become trainers.
