People who were born after the year 2000, like me, will be well-versed in this bug. I learned about it much later, so let's get started.

The "Millennium Bug," often known as the Y2K problem, was a computing error brought about by early programmers using only two digits to denote years (for example, "99" for 1999) in order to conserve costly memory. Experts were concerned that computers would read "00" as 1900 instead of 2000 when the clock struck midnight on January 1, 2000.

This posed a threat to vital infrastructure, such as electrical systems, banking, and aviation. But the anticipated turmoil was mostly avoided thanks to a vast worldwide effort to patch software, which cost an estimated $300–600 billion. As a result, the shift was so seamless that some people thought the crisis was a fabrication.

Aftermath 

The shift was relatively seamless, despite widespread concerns of a digital Armageddon. Large-scale, billion-dollar remediation initiatives around the world avoided catastrophic breakdowns. There were only a few small issues, such as misdated documents and ticket machine malfunctions. But because there was no obvious pandemonium, many people incorrectly thought the crisis was a well-managed "hoax."
