Open problem, but most probably not, given that the universe
appearance emerge from a statistic bearing on a infinite set of
(finite and infinite) computations.

For a reason similar to the fact that there is no algorithm capable of
predicting if you will see an electron up or down when prepared in the
state up+down. But comp makes the "wave" itself resulting from
apparent (for the 1-person) arithmetical collapses.

Ok, but the magic of computational connection can be entirely reduce
to the magic of succession, addition and multiplication of positive
And it is magic, but it is a magic which explains why it has to be a
magic. A TOE which does not postulate the natural numbers is a TOE
without natural numbers. We have to assume the numbers, they cannot be
reduced to anything simpler/
