4) What is the cardinality of "all computations"?
Actually, it is aleph_0. The set of all computations is
countable. OTOH, the set of all experiences (under COMP) is uncountable

Interesting. Do you have any thoughts on what would follow from not
holding the continuity (Cantor's continuum?) hypothesis?
This is the origin of Bruno's claim that COMP entails that physics is
not computable, a corrolory of which is that Digital Physics is
refuted (since DP=>COMP).
Does the symbol "=>" mean "implies"? I get confused ...
