its actually hard for robots to compete with 10 year olds

Two years ago, the Boston Dynamics Atlas could do mid-air somersaults - that's better than most 10-year-olds. https://www.youtube.com/watch?v=tF4DML7FIWk https://www.youtube.com/watch?v=tF4DML7FIWk

  But worse at running then any able-bodied 10-years-old. Comparatively, a somersault is quite easy/well-controlled movement.

For sure, but the paper is disingenuous in their description of the challenge they are supposedly tackling compared to what they actual achieve. Here's an excerpt from the introduction of the paper: "Parkour is a popular athletic sport that involves humans traversing obstacles in a highly dynamic manner like running on walls and ramps, long coordinated jumps, and high jumps across obstacles. This involves remarkable eye-muscle coordination since missing a step can be fatal. Further, because of the large torques exerted, human muscles tend to operate at the limits of their ability and limbs must be positioned in such a way as to maximize mechanical advantage. Hence, margins for error are razor thin, and to execute a successful maneuver, the athlete needs to make all the right moves. Understandably, this is a much more challenging task than walking or running and requires years of practice to master. Replicating this ability in robotics poses a massive software as well as hardware challenge as the robot would need to operate at the limits of hardware for extreme parkour." Here's an example of real parkour: https://www.youtube.com/watch?v=5lp1oS0vXg0 https://www.youtube.com/watch?v=5lp1oS0vXg0 They aren't doing parkour, let alone "extreme" parkour.

But how amazing is it that this is even a thing to consider today

  Well I was very conservative in choosing a healthy 10 year old as a point of comparison. A trained 10 year old can do a lot more. This guy was 7 at the time of filming: https://www.youtube.com/watch?v=1c__4ETI7aM https://www.youtube.com/watch?v=1c__4ETI7aM I'm not trying to diminish the accomplishment with respect to the state of the art of robotics, just bring some reality to the comparison against what humans are capable of.
