Like many subjects in recent times (last 50 years or so), they've gotten really entrenched and dusty because they're afraid to go beyond their well defined borders (and then get more difficult to teach and make industry out of). IHO, from a bigger anthropological viewpoint, philosophy and religion are extremely rich areas of idea prototyping. They came first. They are based on intuition and are good-faith efforts to understand our world. Science came later and was much better at it. What needs to happen culturally is that people need to all be philosophers, they need to have a reverence toward the sacred and toward the cultures that hold it dear. However, they can't let religion, or philosophy, prematurely cut off in their minds what the realm of science can embody. There are long lists of famous scientists that did this, and even they were proven too quick to place arbitrary limits on science and prescribe "everything else" as religion, or metaphysics. To me, philosophy/religion/metaphysics are all "pre-physics" in a way. Intuitions without proofs...yet. The intuitions of many individuals, over many centuries, however seemingly incorrect scientifically, aren't completely worthless. It's like saying art is worthless. They may not explain mechanically how something behaves, but they offer insight and new ways of thinking, which are really at the core of how to truly understand something difficult.
