If earthly humanity survives (strains of that strange song “In the Year 2525” filter in) there will be another one of these on October 10, 2110, ten years after another Y2K-like frenzy over the computational equipment of that era which somehow will have fallen into using abbreviations without much forethought again.

The REAL Y2K will occur on the date 1/1/4294967297, when the year cannot be represented by the 32 bit number.

Unless of course, by then, we have increased to 64 bits.
