Almost 20 years have passed since the corporate world woke up to long-term problems in computer code, which became known as Y2K. Over the previous decades, software developers had used the date 01-01-00 (January 1, 2000) as a convenient hack to make it easier to debug software. The problem was that it wasn’t taken out. So as 2000 loomed, there was a realization that, when the clocks hit midnight, software all over the world could simply stop running. Thankfully, at a cost of a few billion dollars, the software was audited and patched, and businesses went back to worrying about other things.
