But even in 1913 a brilliant mathematician from the middle of nowhere could access a world class mentor. I would assume that this is so much easier these days.

But even in 1913 a brilliant mathematician from the middle of nowhere could access a world class mentor. I would assume that this is so much easier these days. What would stand in the way of a modern day math prodigy from getting accepted into a good program? Or is it about making this more accessible to students who are "merely good" rather than brilliant?
