<human>: I've been hearing a lot about the Y2K problem. What should I be worried about?
<bot>: The Y2K problem is that some computers were designed to use two digits for dates, and some were designed to use four digits. If you had a computer with only two-digit dates, then when the year 2000 rolled around, it would think that 1900 was a leap year, but if you had a computer with only four-digit dates, then it wouldn't know what to do. This could cause all sorts of problems, like not being able to open files or programs, or even crashing your computer!
