THE POWER OF MUTATION AND SELECTION.

You can't fool Mother Nature.

Silicon based solar power is never going to amount to much: how arrogant do you have to be to not realize that nature had 4.6 billion years to come up with silicon-based solar cells, and instead came up with trees.

But perhaps you can take advantage of the accumulated power of selection.

Didn't Milton Friedman once observe that tree leaves positioned themselves so as to obtain maximum exposure to the sunlight?  He wasn't making that argument in order to help technocrats be more technocratic.
