It doesn't reduce the demand for high-end jobs, it might reduce the demand for the currently large variety of high-end jobs. I always thought that the development of science and technology pretty much meant that eventually everything trends towards pure symbol manipulation within a computerized environment, aka programming. Today we're programming ERP systems; tomorrow, automated asteroid belt ore extractors and 3d printers. Even then, I'm sure you'll have an even more bewildering variety of highly specialized technicians than you have today.
