Since there is no other example of life anywhere in the universe that we have come across, we cannot assume one way or another whether Earth is representative of all possibilities of life or not. Certainly on Earth, the biosphere is teeming with life while the other layers which lack the particular biological precursors are utterly sterile. Jules Verne notwithstanding, the deep layers of the Earth do not seem to be hosting any forms of sentient cyber species that we can relate to as having biological quality presentations. We have seen nothing on Mars or the Moon to suggest anything more hopeful. We should not arbitrarily rule out the idea that life is the way it is on Earth for a good reason, and we should not presume to have confidence in replacing biological experience with cybernetic agents without knowing precisely what that reason is. > You might appreciate this short story: > http://www.eastoftheweb.com/short-stories/UBooks/TheyMade.shtml > Yes, I like that.
