Philosophy is what humans had before the advent of empirically-based scientific inquiry. It was always barren, and those practicing it may have at times imagined they were questing in pursuit of the truth but more often, as is always the case with human nature, they were pursuing personal gain. As there's little that philosophy reveals, it's better to dress up scarcity in the guise of obscurantist abundance. We can note that precisely no philosophical notion has contributed anything at all to the advancement of humanity bar two ideas. The first is the notion of self-bounding (Stoic philosophy) and the second is the deservedly famous "trolley car thought experiment" that conclusively demonstrates there can be no concept of morality that fits every possible circumstance. Aside from these two contributions, philosophy has been, and remains, a complete dead-end and a total waste of everyone's time.
