Great post A small remark regarding point (2) of the commercial justifications; it's often conflated that RL "requires" Deep Learning (DL), or that RL is Deep RL, which is clearly a false assertion - one often made by groups often seen as "leading" the field - e.g. OpenAI. It should not be necessary for the future of RL to have such a dependence on DL and perhaps the assumption of DL is leading a large section of research into a local optima and somewhat harmful to research and newcomers to the field of RL in general

Appreciate your posts and looking forward to more!
