He didn't say it takes 10 neurons to compute the action, but ten steps. I am sure he is aware that millions or billions of neurons (? sorry, I am lazy) are involved in those 10 steps. His point is that even if we had those millions of neurons or transistors at our disposal, we don't know how to program them in such a way as to get a result in ten steps. At least that is how I read it.
