One of the things that keeps creeping into my head about sentient machines, the robot future etc etc is this: If they become sentient, and have extraordinary capabilities etc etc ...why on earth (no pun intended) would they stick around here? They certainly wouldn't be limited by the same things we biological beings are. They could just leave into the great expanse - poof, I'm outta here dad! Furthermore, lets say, we become part of the machines (a la Greg Bear's EON / Way universe). The line of thinking and questioning starts to move towards resources. These incredible advances in machines, it seems would be accompanied by incredible advances in resource utilization. The notion of poor vs rich entities would be completely different, in relative terms, than what we think of them today. Our insignificance relative to the machines might not matter in the slightest. fwiw - worth reading David Brin's uplift books - in those the machines seem to generally stay the heck away from bio life forms :)
