Roman numerals are stupid. People tend to pick the ones they like, like MMX, and forget the ones they don’t like, such as MCMXCIX. This is why software marketers like to go from version 9 to version X, and when they get to version XVIII they wish they hadn’t. Roman numerals are stupid, and that’s why we don’t use them any more.
Binary base-two numbers are used by computers, because computers are not as smart as people. When all you can understand is whether UNIVAC’s light bulb #654 is on or off, you count in binary. Binary is not for humans, who are much smarter than that. “Binary dates” are something for computer AIs to keep track of and make jokes about, not human beings. Binary numbers are stupid, and that’s why computers use them and not humans.
Arabic numerals and base ten are awesome sauce. Look at your fingers and toes. GOD MEANT FOR YOU TO COUNT TO TEN. Use them. Embrace them. Someday they may get pissed off when you number a Super Bowl without using them and go away, leaving you to figure out how to do calculus with Roman numerals.
