I feel like the more things I learn, the faster I get at learning new things, and so the number of things I am able to get good at increases at a superlinear rate. So, I don't think it's really an either get good at A or get good at B. It feels more like either get good at A and B, or neither. This is my thesis, anyhow, for how polymaths emerge.
