Without someone doing some philosophy, there wouldn't be any context or meaning for any scientific discoveries - the scope and character of their deployment, the restrictions and normative assumptions involved, would be incoherent and senseless. We've never seen anything like that. Taking the philosophical background for granted does not make it inevitable, however.
Most of that philosophy will be done by writers and lawyers and politicians and the scientists themselves, but the vocabulary and reasoning and such that they use will have come from specialists or pros - often from one or two particular philosophers.
The choice at the larger societal level is not really philosophy or no philosophy, but good and bad, skilled and incompetent, deep and shallow, philosophy. Leo Strauss may have been an academic and "useless", but his philosophy has had quite a bit of influence on the actual conduct of, say, the Iraq war. Malign influence, IMHO, but undeniable.
What I think Keynes said about economic theories also appllies to philosophy - if you honestly claim to make official political decisions independent of all that BS, all that means is that you are slave to one you haven't examined.
