What comes after "convergence?"

We know, or should know that technology does not stand still. The promise of "convergence" has been with us for over 15 years, and is only now beginning to be fully commercialized. This will not be complete for another fifteen. So what could come after? We read today that for the first time a man has controled a computer and simple mechanical devices with his brain. Perhaps we will get to the stage where we can not only replace parts of the body perfectly, but to the point where humans will be able to control mechanical and electronic devices with the mind. We will get to the point when we will be able to access the sum total of human knowledge simply by thinking about it. Of course that will not stop people acting like idiots!
