Questions posed by philosophers may be entertaining, interesting, and thought-provoking, but they are utterly useless because the answers to most philosophical questions mean nothing and have no ramifications.
Consider these philosophical questions:
What if we are in a dream right now, or in a simulation, or in the matrix? Do external objects exist or is everything we see just a product of our minds? What if things disappear when someone is not perceiving them? Does a falling tree make a sound if no one is around to hear it?
Those are all philosophical questions. And they are all futile. The answers to those questions could be in the positive or in the negative, but it makes no difference because it does not affect reality in the slightest.
If we are in a simulation right now, we certainly have no way of finding that out, so it is a waste of time and effort to devote time and effort into contemplating the idea. If external objects do not exist, i.e., if things “disappear” when no one is perceiving them, and if a tree makes no sound when falling as no one is around, is utterly irrelevant, for we can only see things when we are looking at them and listen to things when we are hearing them. The idea that objects may not behave in the same way when one is not around has no consequence to our reality.
My primary concern with philosophy and some of the (ridiculous) answers to its questions, is that it provides no evidence. And it provides no evidence because the questions are phrased in a way in which obtaining evidence is impossible. How could one possibly know if something is there if they cannot measure it in some way? There is absolutely no way to gather evidence to either prove or disprove philosophical questions.
Philosophy is only useful when evidence can be presented for its inquiries of the universe. But the fact that on is using evidence means that the question, or inquiry, is no longer philosophical, but rather scientific -- rendering "philosophy" only useful and insightful when it is science. In other words, philosophy is useless and science is useful.
As Newton's razor puts it, something that cannot be settled by experiment or observation is not worthy of debate. Philosophical questions are, indeed, hypotheses that cannot be falsified, and that is precisely why philosophy is hokum at worst, and trivial at best.
