(Buddhism seems generally mostly unhelpful and often antihelpful, but) What you say here is very much not giving the problem its due. Our problems are not cartesian—we care about ourselves and each other, and are practically involved with ourselves and each other; and ourselves and each other are diagonalizey, self-createy things. So yes, a huge range of questions can be answered, but there will always be questions that you can’t answer. I would guess furthermore that in relevant sense, there will always be deep / central / important / salient / meaningful questions that aren’t fully satisfactorily answered; but that’s less clear.
