Why did philosophy die?

(This is my first post in this sub, and I'm new to Philosophy. Apologies if I made a mistake or used the wrong terminology.)<br><br>Why did philosophy die as an academic subject? For instance, physics, biology, chemistry, etc have made countless discoveries since their beginning. But philosophy seemed to not have made any new discoveries since the ancient greeks. Philosophy used to be integrated into science (it's how science was done), but philosophy is now just mostly humanities and history. There is no modern philosophy, and philosophers do not do any real research in the field anymore.<br><br>I've read that science (empiricism) replaced philosophy, but that's not true. Philosophy should not have been replaced by science, since philosophy does not necessarily have to be about empirical knowledge. Philosophy is literally the study of knowledge, and knowledge does not necessarily have to be empirical. There are countless questions that need to be answered, yet no philosophers are working on them. Take the mind-body problem for example. Despite science's progress, it still remains unsolved and nobody is working on it. I've read countless papers by philosophers, and most of them are talking about other philosophers and their opinions. They are not actually doing research. Give an example of any recent discovery in philosophy, and you can't because there aren't any.<br><br>I'm not saying philosophers have made zero progress. I'm saying that progress in philosophy is in the order of centuries, while other fields it's in the order of months.
