How Do You See Progress in Simulation for Robotics?

In general there are a lot of tools out there and some of them are really very very good. So that is one way that you can do either do robot experiments or it's a way in which you can train a deep-learned robot. I think we cost the threshold of the simulation maybe five years ago or something like that. The sadness is that it will tempt people to do less stuff with real time.
