Well, it's not just a difference in optimization goals; it's a difference in methodology.

Evolution optimizes by using heuristics and stochastic search--piling crap on top of crap, and obfuscating into oblivion.

Engineering optimizes by finding elegant mathematical solutions.

Sorry, getting off-topic. I guess I'm just bitter about not being a robot.

Evolution "optimizes" for a lot more constraints. It needs to be self-healing, and work for a long time without any outside maintenance and monitoring. It collects its own energy, and competes with (unpredictable) other organisms for nutrients and sunlight.

Good luck engineering a system like that. Elegant mathematical solutions are great, but only exist for limited, well-defined problems.
