[Serious] Generally speaking, is philosophy a worthwhile subject of study?

[GrandizerII]

polymath seems to be under the impression that philosophy is in competition with science, but philosophers aren't (generally speaking) trying to use philosophy to do the same sorts of stuff that science can effectively do. And of course metaphysics has its uses, as it can guide and further expand upon what the sciences say, thus hopefully leading us in the right directions when seeking further answers via science.

Can you give a recent (within the last couple of centuries) where that has happened? When has metaphysics pointed a direction to solving a problem in the sciences?

Well, for example, philosophers re-contemplating views on the nature of time in light of the findings of special and general relativity, perhaps suggesting more credence in views that are more in alignment with relativity (such as eternalism or B-theory of time) as opposed to those not backed up by the current science (such as presentism or A-theory of time), or maybe instead suggesting that we not fully discard what our intuitions say and go with a more moderate view of time (like a hybrid of eternalism and presentism).

Another example, what does each interpretation of quantum mechanics say about such things as possibility, probability, randomness, agency, etc. Where to go next with this? How can we get science to confirm any of these interpretations exactly?
