When used to be ok with the fact that things do, in fact, change that’s ok. When used as an excuse to not try that’s a quick way to tower of babbel ourselves simply because there are way too many people who see multiplication in school and ask, unironically, when they’ll ever need it. It’s like people are allergic to having the barest amount of intelligence or putting in the slightest amount of effort.

English works like any language, it has to be at least vaguely consistent to work.
