Rising young pianists: Martin Helmchen, Yuja Wang, et al

[bernadette60614]

Has anyone else noted that there are an amazing number of rising your pianists?  This weekend I heard Martin Helmchen. Last year, Yuja Wang.

This may be old news to everyone else, but it struck me how stunning the technical ability is of these young pianists, and I'm wondering if approaches to teaching have changed or if students with great potential are nurtured from a younger age and/or identified sooner.

Yuja Wang is 31 years old....and she's been a "superstar" pianist since I was like 12. I'm 22 now...

Allow me to rephrase:

What advances have happened in the last 50 years in piano pedagogy which are most notable?
