Let's us try a evolution experiment:
Dismantle one (Handle or Spot) into one hundred parts of hardware, softwares, circuits, nuts & screws, etc
Store the 100 parts in a big gyrating machine, on 24/7 motion.
Wait and see how long would take for the parts to reassemble and evolve into one functional robotics.
1,2,10, 100, 1m years?
(Btw, Handle or Mini-spot (my favourite) would be fun to have around the tool shed)
Is human not infinitely more complicated and sophiscated than Handle or Spot or computers?
Random chance?
