We can say that about programmers, most ICs don't understand what's going on in the layers beneath were they work. Most have no idea what's going on with libraries, frameworks, remote APIs, it's all abstractions. Most people can't tell you how system calls are implemented or function. They don't have the time, bandwidth to understand it all, they just operate at their own layer to get the job done.
