Since it was more for less settled that metaphysical questions can't be settled and moral statements are not factual ("is-ought" problem), the job of modern philosophy is mostly to study the expression of ideas through language. I.e. "what is bit you really mean when you use words like 'god', 'reality', 'state', 'free will'..."

Since your box of answers is expressing complex and very important ideas through language ("Reality is ..."), philosophy will actually be more necessary than ever in order to interpret those answers, or explain them if they are precise enough to not allow various interpretations (if those questions were answerable both concisely and unambiguously, we would have found the answer by ourselves).

Ironically, what became absolutely useless are natural sciences and humanities, since answers are all readily available.
