Panpsychist, quantum based, pictures of reality don't work because they are dualist. Typically in these, the collapse of the wave function precipitates or expresses a quantum of consciousness, and these quanta aggregate via coherence into the macroscopic consciousness of humans and higher animals, etc. Nothing could be more absurd than such a notion of atoms of consciousness in its need to find the kind of thing that consciousness is. Apart from that it doesn't solve the measurement problem, it theorises the objective collapse of the wave function and so cannot account for the strange dependence of such collapse on the way in which the measurement is set up. All the talk of consciousness in this connection seems like a red herring, there is nothing about the subject or self, for whom consciousness..., when it is actually a matter of knowledge. The measurement problem and the phenomena of superposition are better seen as resulting from a consistently applied need to know basis in cognisance of the world. This actually works better with 'reality is a simulation' theory than with 'all is consciousness'. It might be like the infinity problem, with consciousness playing the role of infinity and knowledge that of the system of things from the ground up. Top-down doesn't work because the top is too far away to give any scale to the bottom. Admittedly 'knowledge' invites the question, 'who knows?', but at least knowledge is objective, it doesn't matter who in particular knows, modulo some internal transformations in point of view. One might urge panpsychists to keep their greasy hands off consciousness, if the attempt to grab hold of it weren't such a joke.
