During the three years since the Jeopardy match on TV, Watson has become 24 times smarter and faster, improved performance by 2,400%, and is 90% smaller. IBM says it has shrunk Watson from the size of a master bedroom to the size of three stacked pizza boxes.
IBM says, "What we believe is happening right now, is that the amount of information being produced in the world is overrunning the ability of humans to consume it. When these kinds of things have happened in history, new tools emerged that helped humans deal with scale, such as in the industrial revolution." "I think as we look at knowledge-based professions today — health care, law, teaching — they're all being overrun with information. It's very difficult for people to keep up — and that leads inventors to come up with ways to help humans deal with that overload."
