Well, I assume (reading ahead) that whether or not someone recognizes it
is immaterial. Just to be sure, don't you believe that "computationalness"
like "consciousness" is independent of what outsiders observe or think about it?

I quite agree.

Well, as I said earlier, first, I deny that anything truly random will
have anything at all of substance in it. To me, an almost random
system could indeed contain a conscious mind, so long as it was
not frozen in place, but was causally being computed from one
state to the next.
