It's seems silly to compare it to the y2k problem, aside from the bit at the end of the article: Many older computers, with aspects dating back to before the end of the Shōwa era in 1989, have never been updated to reflect the new era, and still think the year is Shōwa 93. That means Japan could face another mini Y2K problem in 2025, as those systems attempt to tick over to a three digit Shōwa year they can’t cope with. The real problem with y2k was the amount of compiled code depending on two-digit years. All those conditionals looked exactly like any other integer comparison.
