1 year agoTests would be a pretty bad idea. It is easy to imagine the ways that someone could use that to attack their political opponents. Similar things were used to disenfranchise voters in the past. Also, it is too easy to corrupt the legitimacy of such a test. All a person would need to do is get a heads up of how the test works and practice for it. Or, have the test designed to be too easy to pass. It’s easy to say “make it impartial, scientific, and dignified”, but that doesn’t mean it will be. I seriously doubt any governmental body ever has or will be that trustworthy. An actual age limit would be objective and clear though, making it much more practical.
Y2K specifically makes no sense though. Any reasonable way of storing a year would use a binary integer of some length (especially when you want to use as little memory as possible). The same goes for manipulations; they are faster, more memory efficient, and easier to implement in binary. With an 8-bit signed integer counting from 1900, the concerning overflows would occur in 2028, not 2000. A base 10 representation would require at least 8 bits to store a two digit number anyway. There is no advantage to a base 10 representation, and there never has been. For Y2K to have been anything more significant than a text formatting issue, a whole lot of programmers would have had to go out of their way to be really, really bad at their jobs. Also, usage of dates beyond 2000 would have increased gradually for decades leading up to it, so the idea it would be any sort of sudden catastrophe is absurd.
