Why do so few individuals ever reach the highest levels when so many start out on the Road to Excellence? In this book, the world's foremost researchers of expert performance in domains as diverse as sports, medicine, chess, and the arts explore the similarities and differences in the extended and strenuous Road to Excellence taken by the successful individuals in each domain. Their findings will intrigue and inspire readers who are themselves driven to achieve or who simply want to better understand the processes involved.
The Road to Excellence reads almost like a book club among researchers who read Bloom's Developing Talent in Young People and Ericsson's numerous papers on deliberate practice. Each chapter is from a different researcher or group, often with different views. (I was initially a bit put off by the lack of cohesiveness, but in hindsight, I like the resulting feel of authenticity: things get messy at the edge of human knowledge.)
And for anyone who hasn't read Developing Talent in Young People yet, I would highly recommend. The main idea is that Bloom studied the training backgrounds of 120 world-class talented individuals across 6 talent domains: piano, sculpting, swimming, tennis, math, & neurology, and what he discovered was that talent development occurs through a similar general process, no matter what talent domain. In other words, there is a "formula" for developing talent -- though executing it is a lot harder than simply understanding it.

The thing about ageism is just a simple matter of interests. It's reasonable to think managers and teams are looking for the best talent, but it's more like the game show Survivor in that people are looking for talent only up to a point, people need to feel your talent isn't going to expose their weaknesses. So as you get better past a certain point, it really gets worse for you trying to break into new groups.
I read the article you linked and was hoping it contained new research to clarify or refute the work done by Ericsson, but it didn't. The linked article regurgitates two of the key points in The Road To Excellence by Ericsson:
* You need to be engaged in deliberate practice (e.g pushing yourself outside of your current area of expertise). Not mindless work. I'm not an expert driver from my 10,000+ hours of commuting. * 10,000 hours isn't a set figure. It's an average at best. The premise is claiming that people in the top-tier (2%-5%) spent a lot of time consistently practicing their area before reaching the top-tier.
The "10,000 hour rule" hasn't been debunked. It just doesn't mean what some people assume it means when first hearing it refereed to as the "10,000 hour rule".
So here are the numbers, in short, for mastery:
It takes about 10k hours of practice.
It takes about 10 years.
That means about 3 hours of practice everyday. Everyday.
