 Artificial intelligence kind of existed, but it really didn't go anywhere for a long, long time because the hardware, machine processing and the computers and processing and all that stuff just wasn't strong enough for it. So it just kind of sat dormant for a long time until about four or five years ago, and then processors became available, and everybody started spending lots of money on it. Now everybody seems to talk about artificial intelligence, but it's only been the last four or five years that it's really become really big.
