<human>: I've been hearing a lot of talk about the Y2K bug. What is it and how does it affect me?
<bot>: The Y2K bug was a term used to describe a potential problem that could occur when computers were programmed with two-digit year values. For example, if someone entered the date "12/31/99" into a computer program, the value would be interpreted as "00/01/00". This could cause problems for some software programs because they may not recognize the year 2000 as a valid date.
