Game playing is the next frontier. Model economically valuable tasks as games and have the agents play/compete. Alphabench and Vendingbench show the potential of this approach.
The difference is going to be instead of starting from pre-existing games and hoping that "generalizes" to intelligence, this time people are going to build gamified simulators of economically valuable stuff. This is feasible now because we can use LLMs to help generate these games much faster than we would have been able to previously.
