Progress doesn’t happen automatically when the scientific or technical prerequisites for it are in place. It only happens when people work on it, and that almost always requires funding. As a corollary, progress can stall for lack of funding.

In order to improve allocation, we should pay attention to funding models. We may want to improve the models we have, or reallocate our portfolio of them, or bring back old ones that we have left behind, or invent new ones.
