It's easy to think of it that way, even if you were alive at the time as some generations were not. The Y2k issue stems from systems made prior to the early 90's iirc.
From the server side of things, particularly for the machines running critical functions like the stock exchange, the FAA sites, airline booking & sales etc.. This was likely a very critical bug, but objectively from the user side this felt like an awful lot of nonsense.
