> Yes, it's true that all software occasionally has bugs. But when all the software fails at the same time, a lot of the backup systems simultaneously fail, and you lose the infrastructure to fix things.
This is especially important if you think about what things were like in the late-90s. As a teenage geek in Northern Ireland I read about the the first tech boom, but locally there was very little exploitation of tech and you were an anomaly if you had dial-up internet at home. There was very limited expertise available to fix your computer systems in the best of time.
Big companies had complex systems, but they could also afford contracts with vendors in the UK mainland, or Eire, to fix systems. It was much more limited for other companies. While people were generally not relying on personal computers too much, small businesses had just reached that tipping point where Y2K would have been painful. As a result, they took action.
I only got to visit the US a few times in the early-nineties and it seemed so futuristic (I got a 286 PC in '93 to use alongside my Amiga). I imagined the Y2K problem as being much more painful in the US, and I wasn't accounting for the distribution of expertise.
One great experience was summer training courses that the government had organised with a IT training company in Belfast. These were free and it was a like a rag tag army of teenagers and older geeks from both sides of what was quite a divided community. The systems we were dealing with were fairly simple. It was mostly patching Windows, Sage Accounting, upgrading productivity apps (there was more than Microsoft Office in use) etc., but the trainer was normally teaching more advanced stuff like networking and motherboard repair so we spent a lot of time on that.
