@thomasfuchs I worked for 3 years on #Y2K stuff
Here's the thing: many dates aren't point-in-time but past/future. We should have seen the left half of a massive bell curve of failures for 10–20 years before the year 2000 (and before we started fixing it seriously), e.g. mortgages being flagged as 80 years late for renewal, reactors shutting down because their maintenance was 95 years late, etc.
We didn't see that. The Y2K bug wasn't fake, but it was massively overhyped.
