First, he is reversing cause and effect in that AI is a philosophic problem (more specifically an epistemological problem). The philosophy departments have been doubting the efficacy of reason for over a century now, a process that started with Descartes, advanced by Hume and cashed-in by Kant to save faith from reason (i.e. subjectivism). If modern philosophy had been actually working to validate reason and explain how it works we would already have AI. AI is on hold until someone explains how reason works, and more specifically concepts, in enough detail so that we can program a machine to do it.[1]
Second, if you signed up for philosophy courses or a PhD today, perhaps you would learn how to be a more critical thinker but the danger is you would be infected with navel-gazing skepticism and impotence of reason and thus wreck your ability to think, big or small picture. If you are really talented you can get tenure writing essays destroying the work of your colleagues without generating a shred of original work.[2]
[1] Someone from the early work on computers said (I paraphrase); "Show me what the mind is doing and I can make a machine that can think". I want to say von Neumann but I've never found a source for that statement. If anyone knows who said it and where I would be very grateful for a reference.
