Pretty cool! At first I wasn’t that impressed because it’s mostly just pushing to get some speed then “passively” riding down some ramps and steps. Then I realized that riding down steps is not a passive activity — most humans will fail their first time and need to learn to maintain balance while the board bounces over rough terrain.
I think most inanimate objects would fall off a skateboard when pushed down steps, so it’s an impressive display of balance and tool-use in my opinion!
