Oh?

So you're saying Chaitin-Kolmogrov information and other ways of
studying entropy are "wrong"? I think that's a bit unreasonable, don't
you?

There are different definitions that are useful at different
times. Fundamentally, mathematics provides us with models, which are
sometimes applicable to a particular practical problem, and sometimes
are not applicable. It is dangerous to forget that. When you do, you
get things like "proofs of security" based on inapplicable models, and
worse.
