Of course, since this is what computers do. And it is suprising because we
don't know what the results of carrying out the instructions we give it will
be. I never stated that computers don't do suprising things. They just won't
invent something that is not derived from the axioms/the code we give them.

I am not sure that this is true. First, no one yet showed that nature can be
described through a set of fixed laws. Judging from our experience, it seems
all laws are necessarily incomplete.
It is just dogma of some materialists that the universe precisely follows
laws. I don't see why that would be the case at all and I see no evidence
for it either.
Secondly, even the laws we have now don't really describe that the atoms in
our brain are rigidly controlled. Rather, quantum mechanical laws just give
us a probability distribution, they don't tell us what actually will happen.
In this sense current physics has already taken the step beyond precise
Some scientists say that the probability distribution is an actual precise,
deterministic entity, but really this is just pure speculation and we have
no evidence for that.
