When supercomputers are upgraded the amount of information they can process in a second of time increases. Researchers report that between the years 1956 and 2015, there was a one-trillion-fold increase in what a supercomputer could process in a second of time. Our brains, however, haven't noticeably improved their processing speed during the same timeframe.
Speed can create interesting phenomena. Speed has the effect of stretching a second so more can be accomplished during it. It's almost as if the faster something moves the slower time passes. We see this illustrated in the movie Matrix. Neo was taught to stretch time so he could avoid incoming bullets. Today's supercomputers have Neo-like capabilities - they can stretch a second so more gets done.
