There were some systems that would break at rollover. Your ATMs, for example, were probably coded with a two digit year. Databases and any other software codes with a two digit year may or may not have functioned properly after the rollover.
The predominant fear amongst those who knew little about it was that all computer things, hardware and software, would cease to power on or function at all.
Your PROM swaps to make the ATMs function is a worst case issue, but people would have been able to go into the bank and withdraw from a human teller, which belied the fear that their money would just disappear.
The Y2K bug was absolutely real, and things needed to be fixed, but the worst that would happen is people would have been inconvenienced - their money and property wasn't going to evaporate.

I'm confused - is your reply intended to be a refutation of the general seriousness of mitigated Y2K risks, feedback that I could have picked a more illustrative example, or something else?
My post wasn't intended to be comprehensive. Perhaps you can consider it to be an attempt to help close the gap between the technical understanding and the popular one, to mitigate drift of historical understanding.
