Earlier quoted context omitted.
Why is that? Why do you claim not everyone has the potential to become a math genius? Do you have any evidence to back that up (besides Ratatouille)?
Surely you don't mean to suggest that we all start with equal chances of attaining any and all skills?
Any and all skills? No. Mathematical and other related intellectual skills? Why, yes, I do. Despite what most people say, I've never seen a genius who hasn't worked at least twice or thrice as hard as his peers. I've never seen a child that, without the help of any tutors at an early age, or without any influence from their parents, was simply spitting out non-trivial theorems from an early age. I have a hard time believing that some people are BORN better at math and logic than others, and I've yet to see any evidence to suggest that.
Quite on the contrary, I've seen plenty of evidence to suggest that genius is at all not genetic, and that you can train children to become prodigies, and later, geniuses. Surely you've heard of Judit Polgár, universally considered the best female chess player of all time? She was made a genius, not born. Her two sisters grown to become Grandmasters as well. And here's Dr. Frankenstein: https://en.wikipedia.org/wiki/László_Polgár
