I wonder.
If life in this solar system (I'm assuming there is/was on Mars) started as the result of some civilizations nanorobots being either seeded into the Universe or getting away from some attempt to "alien-form) a distant planet.
If the first, we are in effect robots. I suppose if the second, we are robots, too.
Kinda interesting. I wonder what the DNA nanorobots will look like in 50 years.
