Extending the scope of AI decision-making outside of the realm of economics seems much harder, though, as there's much less training data for questions like how to educate students in a pandemic, or whether to loosen planning rules for building wind turbines.
I suspect that before AI becomes capable of providing good answers to those questions, it will already have changed the world beyond recognition, and probably not in a good way. The best we can hope for is mass unemployment and a UBI, which will also make all economic models obsolete too.
