How can we define complexity?

But science is constantly being updated. I am no scientist myself, but would I be wrong in saying that there have been 'scientific facts' which have been deemed outdated when new evidence is found? If so, this speed limit might just be another one of those, true until proven false.

We haven't created the robot yet, but then go back 500 years and ask them if they think man would ever be able to fly around the earth, dig under the sea, fly to the moon, etc etc. The things that we think impossible might well be possible in time. Though for now, we have no such robot, and no such proof or evidence that there will ever be one.

In speculation however, there is a case for it. Think about the Matrix, or I Robot, or any other science fiction book or movie. Humans usually end up creating something more powerful, more intelligent, more self-sufficient, than themselves. Take something like I Robot by Isaac Asimov (the book). At one point a robot is arguing with some humans that he is more suited to the world. He tells the humans that they are outdated, that he is the evolved version of them. Why? Humans have to eat, robots, don't. Humans have to sleep, robots don't. Humans can get hurt in innumerable ways, robots can't. Sure, robots have to be created by a human, but suppose that in the end we created a robot to build a robot. It becomes the matrix. And all of a sudden, we've got a creation more powerful, more intelligent, and more complex then his creators.

But then again, it's all just speculation.
