I’m late to the party but I’ll drop the truth at the bottom: computer science in its own right is just modern philosophy of mind. It’s the specification of the conceptual limits of cognition.
I love his “sociological sense”, and agree that at some level all these words are just words in language games that are defined with great diversity across the world’s academics, much less engineers and laypeople. But I also agree that there’s something worth defending in “computer science in its own right”, as I said above; that is, in turn, the core task of philosophy of science.
Of course I would expect him to push back on this description of the field because philosophy has lost all its street cred, but that would only encourage me to redouble my efforts. If it’s not empirical study of actual results, and it’s not mathematical study of intuitively-based theorems, what else is left?
