The robot (BigDog) in that video shows numerous capabilities that Spot still can't do (climbing over terrain like that, being able to respond to a kick like that, the part on the ice, etc.). Even 16 years later.

This only highlights the fact that making a cool prototype do a few cool things on video is far, far easier than making a commercial product that can consistently do these things reliably. It often takes decades to move from the former to the latter. And Figure hasn't even shown us particularly impressive things from its prototypes yet.
