After a few hours of messing around with maths, it appears that the chance of going extinct doesn't increase as the total amount of humans born so far approaches N, and that the higher the total amount of humans born so far gets, the higher the chance of extinction before we reach N. This makes sense, as we can never reach N. This is evident by N's definition. N increases faster than the total amount of humans born so far does, as i showed in my previous post. So as there is a 100% chance of going extinct before we reach N, we can say that N < (1/(1-1))n + (1/(1-1))x. As 1-1 is 0, and y/0 is undefined, we get N < undefined.
