No, it is not the combination by chance, it is, on the contrary, due
to the extreme richness and complexity of the relation between
numbers. It makes it possible to take the numbers, when structured by
addition and multiplication, as the source of the emerging very long
and deep computational histories, themselves filtered, and non
trivially restructured, by they possible self-aware universal numbers.
No chance is at play there. That is even why you can extract the
physical laws and justify why they are laws.
Probabilities appears as internal first person modalities because no
machine, and thus not us (assuming comp) can ever know in which
histories they are. They can know this (betting on comp), and they can
infer that they are supported by many histories, leading to a many-
world interpretation of arithmetic.
Monkeys on typewriter authored all the books, like a counting
algorithm. You can say it generates all programs, but it execute none
of those programs. The monkeys will generate books describing
computation, but never any non trivial computations.
The universal dovetailer, and the arithmetical truth (actually a tiny
part of it) not only generate all programs, but execute them, in the
platonic static sense, but still, the arithmetical true relations
defines computations, not just description of computation.
Look at the Mandelbrot set link I give to Kelly. There is nothing
really random in that structure, yet the more you zoom in, the more
intricate the structure appears. You can perhaps intuit that something
is evolving there.
After Gödel the mathematicians have to abandonthe idea to ever find an
unifying complete theory of the numbers with their additive and
multiplicative structure. The monkey's type writing is trivial.
You cannot faithfully embed computer science in the numbers or in the
monkey's typewitting, but you can fully embed computer science in the
additive and multiplicative structure of the numbers. It is lawful and
unpredictable by complexity and deepness, not by chance and randomness.
Monkeys = numbers = not very rich.
Universe emerge not from numbers, but from the logical relations among
the numbers. That is so rich that there is no TOE for that!
