    We need to make people focus back to RL again

    Extremely interesting, the part about being less aggressive when prediction is harder kind of reninds me of some speculative thoughts I had about artificial neurotransmitters aping the locus coruleus norepinephrine system to control error rates of subcircuits to speed up learning, that idea is still underdeveloped though and I was thinking more about optimizing the joint relationships of different routes into a neuron which would have atrocious scaling done naively.

    A very nice overview. What is a good place to learn it from code examples?

    Thanks - I haven't been tracking RL for past several years, so this is a nice high-level update on things, with linked papers for details. Given this progress, are we about to see an explosion in robotics deployment? If so, will it be mostly industrial, or some consumer impact also?

    I'd bet that the consumer impact will be there before this will be picked up by "industrial" applications. Industrial applications are so stuck in the 70s style static robot programming with SPS and ladder logic that they will be extremely late to the game compared to startups and research already working with AI/ML. Also, this will have the most impact on small to medium size companies. Big companies can already afford an expensive robot programmer to the do the programming of the industrial robot, small companies simply can't, so they will benefit most from easier (and therefore much cheaper) robot programming. The hardware might still be expensive, but the current reality is that programming a robot is much more expensive than the hardware (even something like a UR isn't fully end user friendly and requires expert knowledge of some level).
