I think he means Oracle as in general powerful question-answer, not as in a halting oracle. A halting oracle could be used to answer many mathematical questions (like the aforementioned Riemann Hypothesis) though.
I know he doesn’t mean a halting oracle. A halting oracle is a well-specified superpower that can do more than real Oracles. The thought experiment I described considers an upper bound on usefulness of Oracles.
