That might be true in some cases, but I think that in the vast majority
of cases, Y2K bugs were caused by sloppiness.
After all, I can encode 256 years in one 8-bit byte. So please explain
how encoding a mere 100 years in two bytes saves memory!
Furthermore, show me the documentation that explains that this was an
intended limitation, and the reasons for it. Show me the code that says
"Max_Year: constant Year_Number := 1999; -- ....". I'll bet that in the
vast majority of cases, nobody bothered to write anything like that
down, which supports my "sloppiness" claim.

The techniques needed to properly encode limitations such as the y2K
limit have been known since the 1960's, at least. The fact that they
weren't used is no excuse. Changing the limit from 1999 to 2099 or 9999
should be a one-line change, and it shouldn't cost millions of dollars
to find that line.
