One implication for products, if this work pans out, is that the systems which "adapt to you" (learn your voice, your schedule, what your face looks like) won't have to change the weights of their network. I believe this could lead to much better systems because adjusting the weights of an already-deployed network is dangerous - you could make the system perform poorly. It's also simpler for engineers because you can scrap all that logic and just deploy one RL network.
