I was thinking of Heisenberg's uncertainty principle, when I wrote

the hold that Heisenberg portrays. I am betting that all things are
computable and there is nothing that can be considered non

it human spit, or a galaxy, are all based, or derived from
computation. Indeed, that a great computation set off the Big Bang,
and that computation yields everything from stones to stellar gases.
Am I convincing? No. Because I am stating what I suspect is true.
Any and all may disagree. Can love be computable? Well, yes, or at
least aspects of it. Moreover, I don't see where all things cannot
be computable.
This is not a life-long belief, but something I arrived at recently,
after viewing papers and articles in physics and computing. If its
all numbers organized into equations, and equations arranged into
coding, I can't see how I can be wrong.
You described the point which starts this all. But you seem to forget
the FPI. The idea that the whole of physics is computable is
inconsistent. It would entail that "I am computable", and this
entails, by the FPI, that physics is not computable a priori (or that
my generalized brain is the whole universe).

GOL is deterministic. Quantum mechanics (under any interpretation)
results in true randomness which is not computable. For example, it
is impossible to predict if an isotope will decay in a particular
time period. Under the MWI quantum mechanics is deterministic: the
isotope will definitely decay in one universe and not decay in
another. However, an observer cannot predict which universe he will
end up in, so non-computable randomness returns, despite the overall
determinism.
