[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.
