I started to reply in detail to your comment, but I have decided to stop because there is so much wrong with it. So, I'll leave it with the following, Biological systems are: highly complex self-replicating self-refueling, low-power, low-speed, highly manoeuvrable Our attempts at replication of the abilities lead to brute force high powered, simple non self-replicating, non self-refueling low manoeuvrability needing high speed to achieve same goal And we know very little about biological systems and most of what we know is probably wrong as well.
