<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 is a problem that could occur when computers are expecting to see two-digit year values (e.g., 1999, 2000) but instead encountering four-digit year values (e.g., 19999999). This can cause problems with software programs and other systems that rely on date information, as they may not be able to correctly interpret the year value.
