when they invented the square root of negative one they realized that it was actually going to be useful. so they came up with an entire field of math for it and gave it a letter, i.
there's this other idea, dividing by zero, that also seems just as absurd. but when the day comes that someone makes something useful out of x/0, they will assign a letter to that too and prolly invent a whole new field of math. go git ur nobel prize.
