Playing with MuJoCo is a lot of fun. I recommend it for people who just want to experiment with RL. You can do random weird stuff like this: https://www.youtube.com/watch?v=e-9u_vepfY8. I'm really glad DeepMind is continuing to update it.

Holy Molly. The live demo where you put a place holder and the trained robot dog just goes there is insane! You can also apply force (aka kick) the robot while it is moving!

Really cool. If we could do sim training to rl conversion in robotics, we migth get a llm moment for robotics, with good pretrained movement algorithms.
