Asking a question can have many purposes asides simply answering it. I think if a philosopher thinks they are definitively answering important questions, they're perhaps engaging in a bit of hubris, and while that may have been more appropriate in earlier centuries, I doubt very many in the modern day fall into that kind of self-important trap.

Coming up with hypothesis and working out the brain with new methods and ideas is important in other ways, you simply don't need that sort of certainty that belongs more in the arena of faith. Call them "answers" or whatever, that's fine. The purpose is not to arrive or convince, though, it's to strengthen through exercise and come up with new things. Much like how martial arts is no longer as useful for self defence in a world with handguns, but instead makes for very good exercise and social connections, and is just fun.

Not that philosophy cannot answer any questions, mind you. But I don't think that's very important anymore when more rigorous methods exist. Finding answers is a very small thing philosophy can accomplish, that is minor and unimportant compared to the much more valuable things it can do for a person's skillset. If it did not contribute to skillsets in a very efficient way, I doubt it would have much relevance anymore.
