Universities seem to be struggling to cope with the depth of knowledge that has accumulated. It is empowering to "know how those things work" from first principles, but as time progresses, the volume of such knowledge grows towards and beyond the capacity of the courses that convey it. Universities must then (as they are now) make a delicate balance between covering fundamentals (which most practitioners consider too "academic") and preparing graduates with skills that they can immediately apply in practice. Many graduates seem dissatisfied with the balance that universities choose.
