Seems you didn't really digest what I said, I understand philosophy just fine. You've quoted one sentence out of context and pretended I said all philosophy is wasting time on unanswerable questions, I didn't. Additionally your last sentence makes it utterly clear you didn't actually read my entire reply as I said philosophy's greatest achievement was science, so to ask if I know science is natural philosophy is a dead giveaway you're not paying attention at all.

I commented on that specific line because that exact sentiment is all too common, and entirely unjustified.

And I just justified it. "Unanswerable questions" != philosophy, I was critiquing a subset of philosophy, the useless subset, like arguments for God's existence, useless nonsense asking meaningless questions.
