I think the point is that before, if you had a computer, you had the ability to inspect, modify and program, and with curiosity you'd learn. Now, most people get computers where those things are forbidden. You still can get "programmable" computers, but you have to do it explicitly. Before, it was implicit. So there's a filter that some people won't pass and won't learn, and the pool of people shrinks.
