I don't see Rice's Theorem as directly relevant here, because it
doesn't tell you anything about the quality of probabilistic reasoning
achievable by practical intelligent systems under realistic resource
limitation; it's an uncomputability-in-principle sort of result...

You have not demonstrated this statement or even argued for it, you've
just stated it...

The idea that evolutionary programming is somehow "nontraceable" in
its production of results is a misconception. Ev. prog. is a
deterministic algorithm and if the intermediate steps in the evolution
process are logged, then it is perfectly possible to mine these logs
and understand why a given answer was arrived at. In fact, mining and
analyzing such logs (albeit usually in relatively simplistic ways) is
the principle underlying Estimation of Distribution Algorithms, an
important subfield of ev. prog. today.

a) you have not demonstrated this or even argued for it, just stated it

b) I don't know how you are defining "smarter than" in this statement...
