Y2K was a real (potential) problem which didn't have consequences because a bunch of people did a bunch of work to avoid it. To give a brief description, dates were commonly stored with two digits for the year to save on disk space because the "19" prefix was assumed. Once 2000 got closer people started to realize this mistake. More similar to what will likely (and "suddenly") be big news around the mid 2030s: https://en.wikipedia.org/wiki/Year_2038_problem https://en.wikipedia.org/wiki/Year_2038_problem I imagine most people with knowledge of these subjects would consider them to be unrelated.
