I have seen the talk and may have read the paper, but I remember it mostly for talking about the relation between entanglement and measurements but not for addressing the fundamental nature of particles. But even without rereading the paper I have another point that may cast some doubt onto the idea of the wave function being fundamental. There seems to be growing evidence that space and time are not fundamental which, in my opinion, makes it sound rather unlikely that the wave function will turn out to be the fundamental building block of the universe given the extend to which it depends on these concepts. Essentially I think the most honest answer right now would be to say that our understanding of physics is far from good enough to tackle the question of what is really fundamental and what is just emergent.
