 I know. Please. We all know that. 35, 38 years ago. But he was writing a disk operating system, and then when he would have a DOS ready, we would sit down and try to break it. We would try to make a bug happen, and once we had a bug, he would fix it. That's the way you would go through and make sure the software could happen, and it would not affect the end user's performance of that software. And again, at the end of the day, you don't send it out until you know that you can break it anymore.
