When you assume 8 hours a day straight work 10.000 hours means 3.42 years including weekends. I'll claim that's impossible (not to say inhumane) to do with a child.

That's probably a little aggressive, 4 hours a day is more typical.

Go take a look at the history of Magnus Carlsen, Fabiano Caruana, or Hikaru Nakamura.
