It is pleasant to read, but I will wait what others can add, if it is really more than a variant of the vacuum fluctuation approach.

It cannot satisfy a theorician of mind, who assumes the computationalist hypothesis, because it assumes:

1) the quantum description of the physical reality,
2) a primary physical reality.

I will try to have a look but you just bumped it down my reading list. It sounds like it starts off already high up the ontological tree and hence isn't really addressing what it claims to (Also, anything on CEN which doesn't mention ToN in the credits is off to a bad start, IMHO).


Yes, but it is frequent with physicists. They just work in the frame of the Aristotelian metaphysics/theology. They take the physical universe for granted, so "nothing" means some physical nothingness. With QM, the physical nothingness is already Turing-Universal, so they assume a particular universal system, and they induce it from observation. But with computationalism, and the mind-body problem in mind, we need to explain why it seems some universal system took an importance in the observable realm. Obviously the author just ignore the mind-body problem, or the 1p/3p relation problem, but he is far from being alone: it is a tradition since more than 1500 years.
