As practicing physicist myself I would like to respond to your comment "Feynman’s big problem was that philosophy isn’t physics. His other big problem was that philosophers aren’t physicists.".

I think that there is truth to this and further Feynman while perhaps a bit crude and too dismissive of contemporary philosophy was right! Having spent some time reading studying contemporary philosophy, my main critique of most modern attempts at philosophy are exactly that they fail insofar as the authors are ignorant of modern physics. I would go so far as to say probably most of what we call philosophy apart from maybe ethics, cannot be addressed without an expert knowledge of the main branches of physics. There is a good reason physics and philosophy were born together. To give one example if we consider Derrida's abstruse navel gazing about binary opposites and "logocentrism" all of it dissolves as either trivial statements of well understood truths or pompous nonsense if you have modicum of understanding of modern information theory. I think this sort of ignorance is what helped drive the so-called science wars of 90s.

That's not to say that all contemporary philosophy is without merit. I think for example the Frankfurt school's critiques of enlightenment address a big problem in modern civilization caused by the collapse of religion and ascendancy so-called rationalism. These problem seems too be largely ignored by most scientists despite its importance for our very survival as a species. So I believe we desperately need philosophers who are first experts in modern physics otherwise they will be unable to even discuss basic questions in a sensible way.
