I hate when cryptomining is described as "solving extremely complex mathematical problems." That makes it sound like math professors gathering around a conference table burning the midnight oil trying to crack a formula when in reality it's just trying to crack a safe by randomly guessing the code over and over again - nothing complex about it.
I get your point, the calculations are generally just arithmetic, but there are in fact many cryptologist who spend a lot of time and effort understanding these algorithms and finding ways to "crack" them.
