[Brent:]And even if it is clear that doesn't mean it exists. The
question is whether a value of a variable that satisfies a

different kinds of existence and the existence of numbers doesn't
entail the existence of electrons.
I think we agreed on that a while ago.
I am with you on this. Don't make people believe I could not.
Arithmetic explains only the virtual reality, and if correct, the
physical reality is an appearance of some normalizing procedure. It is
open if that converge to one (class of special) universal number or
not. I think quantum computations win, but that remains to be tested,
both in comp, and in nature.
