The choices via von Neumann’s "abstract ego" are not limited by the known rules of quantum theory
That amounts to saying QM is not sufficient to explain biology.
What's wrong with avoiding Copenhagen references to an "observer" by having wave function collapse through decoherence? Or Bohm's deterministic interpretation which is in many ways superior to the Copenhagen interpretation?
I don't beleive that QM sufficiently explains the mind in whole, in fact quite frankly my personal opinon is that we operate in a "classical" sense almost all the time, this would be equivalent to "thinking" which I consider to be a passive process, concousiness kicks in in active, attention based mode when anomolies appear in the wave like interactions between our predicted inputs and our actually received inputs, which I beleive can be mathmatically described quite beautifully in a model I'm currently building, neuron spiking in my mind is simply the "wave crests" of these interactions as they occur and my model its biologically consistent with some minor changes to the "model" neuron, which begs for very small subtle changes which have tremendous impacts when considered on the whole, the ideas are strictly research based.
Decoherence is fine with me, in fact kill Copenhagen ( which in my estimation is quite subjective ) and use many worlds/universes, pick your collapse methodology, Neumann never specified between the yes and no choice at all in his writings. The choice being made by nature at large, his point was that the choice of
which specific question would be posed what was in the hands of the agent, and that that the choice made "observes" a "quantum like probability rule".
I am a Bohm fan. His pilot waves are beautiful and well defined mathmatically, they are lost in his infinite tower and implicate order, and is less mathmatically appealing, perhaps I have a naive understanding of it.
In summary, I'm trying to integrate and model a system that exihibits mind/brain interaction in a testable way. Biological significance is important and a factor, but if someone asked me to built a locomotive device and the wheel did not exist, i wouldn't be upset if my rapidly moving 4 legged running robot failed, I beleive in a quantum like computer, I'm sure it can be modeled and created in software, and I don't feel the desire or necessity to approach absolute zero or flip atoms around to do it.
