Steven Dick said, "How likely is it that such a robotic race exists? ... greater than 50/50." That is simply his random guess based on nothing but hype and dreams. There is no evidence of any life in the universe besides Earth, let alone any form of intelligent life. If you examine the unique qualities of Earth which allows our life to exist, the odds of such a location existing elsewhere are staggeringly low. Scientists admit the chance of life actually spontaneously occuring on Earth is low; we really are not sure where or how our life began. And even if life should exist elsewhere, why do we think it would be more advanced than ours? I agree we have seen and will continue to see incredible advances in technology. 100 years from now life will definitely look different. Yet life will still be similar today, since our human foibles have been with us for thousands of years, and no amount of technology will eliminate that aspect of ourselves. Robot aliens? Great idea for sci-fi books; lousy science.
