The Future of Quantum Mechanics

Copenhagen is not one of the things that are taken seriously when it comes to found formulations of quantum mechanics. Now there is a sort of post Copenhagen school of epistemic approaches to quantum mechanics, which is more respectable than Copenhagen. But I still don't think they make any sense in their current state because you haven't told me what an agent is. What is an agent that has experiences? How do I model that mathematically? That's just not what I do in physics or in science generally.
