A good idea, but I don't see that these "predictions" of
computationalism have actually been derived. I think most of them are
aspirational. For example, what is the proof that spacetime is
continuous - in fact what is the proof there is such a thing as spacetime?

Bruno has often spoken of the confirmations of computationalism known
to date, and of the idea that it has passed many tests and not been
falsified so far. I was hoping with this post to gather a complete
list of those tests. What things in physics would disprove
computationalism, and what tests has it passed so far? Below I try to
collect a complete list from memory but it may be faulty. I ask that
others might add to this list or correct things I have gotten wrong:
Tests and statuses of each test:
* Non-emulability of physical laws
o Non-discreteness (continuousness) of space time --- (somewhat
confirmed
<https://phys.org/news/2015-03-einstein-scientists-spacetime-foam.html>)
o Infinite computation needed for tiniest amount of space ---
(mostly confirmed
<https://physics.stackexchange.com/questions/222858/feynmans-question-on-the-mathematical-machinery-underlying-nature>)
* Quantum Mechanics
o Uncertainty principal (inability to collect exact and complete
knowledge about environment) --- (confirmed
<https://en.wikipedia.org/wiki/Uncertainty_principle>)
o Indeterminancy --- (appearance of randomness is confirmed
<https://en.wikipedia.org/wiki/Quantum_indeterminacy>,
explanation for being an "appearance only" i.e. first person
indeterminancy vs. fundamental randomness is made is plausible
<https://en.wikipedia.org/wiki/Many-worlds_interpretation>)
o Born Rule?
o Quantization of Energy?
o Unitarity
* General Physics (I am not sure if these are required by
computationalism, and could use some more help on these)
o Linearity of physical laws?
o Time reversibility?
o Conservation of Information? (e.g. black hole information paradox)
o Finite Description of Quantum States (e.g. Bekenstein Bound
<https://en.wikipedia.org/wiki/Bekenstein_bound>)
o Link between Entropy and Information (e.g. Landauer's
Principle <https://en.wikipedia.org/wiki/Landauer%27s_principle>)
o Existence of a "Time" dimension?
* Consciousness
o Qualia - The non-communicable nature of some observations ?
o Finiteness - (finite memory / age / information content of
experience)?
Are there other things I am missing? If any of the items I have
included are incorrect I would greatly appreciate any correction and
further insight.
Perhaps most interesting are any predictions which are presently
unconfirmed, as this would lead to predictions which could later be
tested and lead to a refutation of computationalism (or if passed,
yield further evidence for computationalism).
