Hey good post, well thought out and it's actually quiet an interesting topic to think about. The idea of robots making smarter 'babies' through 'sex' is often vexing for me because I find myself wondering if it is possible for robots to ever recreate the true random nature of the selective pressures that force life to evolve. That is to say, if they could ever force themselves to evolve or if it would just be a natural consequence of their attempts to enhance themselves.
