The article gives a concrete example in the same paragraph: "For example, AI algorithms could get close to a solution quickly and efficiently, and then the gap between the AI answer and the true solution can be filled by high-precision computing." Interestingly the example is backwards (statistical reasoning first, hard reasoning second) compared to traditional usage of "hybrid" in AI and control contexts.
