Here’s a reminder that Y2K was real. It wasn’t a conspiracy theory. Computers were going to crash when we hit the new millennium.
The reason you don’t remember it (and the world didn’t crash) was millions of coders working around the clock to fix it. It was a huge project across multiple countries.
In the countries that did not spend resources on their codes, they did lose their stock markets temporarily. (I know Germany was one. I think Singapore was another.)
This wasn’t a made up problem. It was a problem that we solved with a lot of work. Please don’t dismiss it as nothing or a fever dream.
