      Reinforcement learning is a paradigm that will eventually be superseded. We just haven't figured out what the new, more generally useful, paradigm is yet. When we do, there's going to be a revolution. It will be very interesting.

      Is your issue with the problem formulation or with the current set of algorithms? Most of your critique seems aimed at the algorithms, not the formalism.

      It's really about the problem formulation. I think it's holding us back.

      The algos are inadequate to address the problem formulation, and the problem is misleading & counter-productive (in particular reward maximization, static separation between agent & environment, lack of distinction between behavior programs & behavior program generation)

          @fchollet please say more about your last two items: Why is separation between the agent and the environment a problem? What is the distinction between behavior programs and behavior program generation that we need?

          1) An agent is not a static set of possible actions and reward variables. Its affordances change over time: the environment becomes part of the agent. A clever agent will actively seek to gradually *own (absorb) more of the environment* over time.
