In one of his papers (Undecidability, Fractal Geometry and the Unity of Physics, 2020), he dismisses Schrödinger's equation as being problematic for his theory (because it's linear so I guess "easy" to work with). And I'm no physicist, but I don't really get it: isn't the equation essentially the culmination of the physical reality of particles having complementary properties? So in that sense, isn't uncertainty baked into our reality (and thus still ontological)? Even ignoring all the weird stuff that happens with entangled particles, spooky action at a distance, and all that. I literally cannot measure both the momentum and the position of a particle to an arbitrary position simultaneously.
