What would the world be like if you had to develop a power yourself before you could use it? Just as a silly example: How would the comment section on YouTube change if, to use it, you had to have the schooling necessary to have a basic understanding of how computers and the internet work? More seriously, would anyone smart enough to know how to design and build a tank, or a laser guided anti-aircraft missile, or a computer and video editing software be stupid enough to join ISIS? In fact, if such knowledge was required—would it even be possible for there to be standing armies?
