However trivial the word existence was to Minsky, he believed that
"this" the reality he found himself in, could be the result of a
computer programming that was not even running, just because it is a
set of logical possibilities. To me, this sounds much closer to what
Bruno describes, our being computations in arithmetical realism, then
it is to your dictum that only physical computers cab do anything, and
only if they're turned on and change and use energy.
He says "that's where we have to stop" not because it doesn't make any
sense, he explicitly says the opposite, saying "that's the only kind
of existence that makes sense".
Of course whatever happens is possible. But it doesn't follow that
whatever is possible happens.
