What I meant by pace of fraud: think of US military R&D around World War II and the Cold War, vs. now., and whether they translate into anything actually useful for the soldiers in the field. What I think is a big part of the difference is that back then, US was fighting with peer powers and it was possible for it to lose. Over time, it transitioned to only fighting wars with much weaker opponents - wars with no "lose" condition, where the only variable is how much money the US is going to spend on any particular conflict before getting bored and recalling soldiers home. The latter kind of conflict doesn't create much of pressure to deliver working solutions, or even test bed to verify them.
