Maybe I'm misunderstanding you, but it sounds like you're suggesting that philosophy can talk about anything that science can. And of course, it can, in the sense that there will be uni positions for talking about just about anything in philosophy department, but I'd say that for a long time now when science is able to treat a subject, philosophical investigation of it becomes meaningless pursuit of words, disconnected from reality. And just like religion used to answer some questions about how the world works, but over centuries was in perpetual withdrawal up to the point where it's not its domain at all anymore, philosophy in areas of empirical reality is expected to be superseded by science and as such seems to be as worthwhile as ancient talks about arche and medieval religious talks about creation of the world. What understanding did we gain from arguing over whether the world is made of fire, of water, of ether/whatever? Whether it's deterministic or not? None.
It seems it would be a better use of everyone's time if philosophy withdrew from areas of current and future scientific inquiry.
