Programing math predated computers by over 100 years. So... it is possible. However those programmers would all be "root level access" and therefore not as useful for modern day "hacking". Basically the difference between an engineer who designs cars and mechanics who can mod and trick out a car.
Isn’t it cool that people doing complex math equations were called computers before they invented the machines? 😃 or it just be my dorky self eho finds it interesting.🤷🏻♀️😂
