What is this "everything" which is "computational" ? Specifically,

(I think when erasing) raises entropy. Starting with something that
is ill defined doesn't bode well for the rest of the theory.
You should ask these questions of Bruno. ;-)
Unfortunately, Liz raised questions that I asked, and eventually got
an answer by Edgar, but which were nonsensical proses. Like his answer
to Liz right now.
In his "friendly" post, I just saw that his "theory", like the one by
Craig, seems to be a reification of an 1p view. (a common thing with
"Heracliteans).
But Craig's reification bears on the 1p, and Edgar 's seem to bear on
the 1p-plural. Then, those reifications are accompanied by some
ignorance of the theories involved, and a difficulty to assess the
facts.
BTW, computations does not *need* energy. Only erasing information
needs energy, *when implemented physically*, and we can build Turing
universal system which never erase information, so we can build system
computing anything, and never using more energy than the one needed to
build the system and trigger its activity. But this will not help
Edgar. Then computation per se does not need energy, as a computation
is not a physical notion at the start.
