I was seeing on social media last week that apparently there are a number of people who thought the Year 2000 Bug was some make up thing, because nothing happened when 2000 came around, as opposed to the reality, that a lot of people worked to mitigate the effects.

A week later- some of those fixes were short term enough to fall over when 2020 comes around.

Apparently a non-trivial number of systems are experiencing #Y2020 bugs. A common Y2K “fix” just postponed things by 20 years, interpreting 00-19 as the 2000s and 20-99 as the 1900s. 20 years is now up, some of those systems are still in use, and they think it’s 1920. Oooops.
