actions and you think simulation is ultimately the biggest way that that though those methods will be successful in the next 10 20 years we're not talking about a hundred years from now we're talking about sort of the near-term impact of RL do you think really good simulation is required or is there other techniques like imitation learning you know observing other humans yeah operating in the real world where do you think this success will come from so at the moment we have a tendency of using physics simulations to learn
