It would've been impressive 15 years ago. People seem to forget that first humanoid robot capable of competently walking was showcased by Honda 26 years ago. over 20 years ago, the updated version was capable of running and climbing stairs.

So a purpose-built (look at the thing - running is all it can actually do) two legged fast running robot doesn't seem all that impressive today. Cool? Sure! Useful? Not so much. Impressive? Whatever... it's just showing off at this point, much like Boston Dynamic's Atlas series that went nowhere (in contrast to this machine: this one did half marathon distance:)
