Right, but is parkour a well-understood problem with formulas and solutions? I think there's also a tendency to go "You just need linear regression" a lot when actually, well, there is a reason people are excited about new AI techniques: they make things that were very difficult much easier, and they make some things possible that never were before. Is deep learning / reinforcement learning actually useful here? Maybe. I would be surprised if Boston Dynamics wasn't at least looking into it.
