Talent Development happens in AoPS now, via classes, books, and forums. Also there is a network of high-school student-run math contests, with older students coaching junior students. There are several active Discord Servers.

There are paid online courses as well as free purses run by students, some of whom are trying to polish their resumes for college apps.

We are in a golden age for student mathematics study.

What's missing is a strong environment for youth mathematical research. There is a collection of summer camps, but they are too few and expensive.
