—“How do you demonstrate that the universe is a mind?”—Sam McPhail
For the equivalent to calculation to exist requires possibilities (disequilibrium). For mind to exist requires and a means of storing state, and (a) prediction, (b) permutation (c) choice (d) action from a history of states.
The function of what we call mind is to allow us to predict candidate actions such that we can outwit the determinism of the universe and capture the energy thereby resisting entropy.
How the universe or anything in the universe can do something, or anything, close to ‘mind’ would require we discover the means of information storage and the means of using that information storage, and the possibilities predictive using it, and the means of selecting choices from those possibilities, and the means of acting to seize those opportunities (choices), for some purpose (caloric gain).
As far as I know the universe is purely operational (limited in transactions) at every scale. And that our current ignorance because of our inability to measure (observe), has left us uncertainty as to whether the universe and its contents are the same or separate things, and whether there is one or many, and whether they are interdependent (frothing so to speak).
