I've found another one of Campbell. He opens the possibility for Consciousness only using a
simulated free will or limited free will, source is -> here:

"I suggest a simulated free will is free enough to make our virtual PMR an effective school.
That is practical free will and uncertainty is a built in feature of the system — there are always
unknowns. Jumping out to AUM’s level, the complexity is so immense -- imagine an analytic
(deterministic) function with a billion trillion independent interactive variables — a space with
a billion trillion dimensions, i,e,. orthogonal unit vectors . Lots of choices where the outcomes
may well be unfathomable to a finite AUM.
"


AUM is the EBC (Even Bigger Computer), all there is, Digital Data, Consciousness.

According to Campbell, a simulation needs the input of free will to make a working,
unpredictable simulation. If no unpredictability existed, AUM could just calculate the
result in advance, without the need for a simulation = running physical reality with
live entities who contain free will.
