Our culture has an awkward relationship between talent due to genetics and due to hours and hours of practice. Props to the author for creating this. But part of me feels like this book is slightly too heavily skewed in the direction of thinking that genetics is more in control of talent rather than practice. Why do I say this? Because it seems to believe that there aren't implicit ways of improving brain capability through the use of, for instance, mathematics. By teaching the child what it is you want them to know directly, instead of concentrating the attention on, for instance, developing their imagination (without the constraints of having to anchor it in programming), you're essentially placing a vote on the belief that the child won't be able to pick this stuff up easily once you've built their brain up.
