How many IT people have you asked? Because it’s not hard to explain.
Lots of systems and software didn’t account for needing 4 digits to write a date. People built fucktons of software on the basis of only needing 2 numbers to describe the date. Without the additional two digits systems would interpret things as happening in the past that were actually representing dates in the future which would break things. All you need is code that contains a basic if function, “If, today’s date is < other date, reject input” and it would render a load of software unusable.
The computers aren’t inferring anything, they’re not sentient they’re just following badly written rules where the people coding didn’t think far enough ahead.rom 99
As others have said the reason people have some conspiracy about it all being bollocks is largely because people did a hell of a lot of work to fix the issue.
