Just because it isn't as bad a joke would imply doesn't mean it still isn't really quite bad
Base 12 vs base 10 is pretty much the only objective advantage of USC, and it only uniquely occurs in USC for small construction-scale tasks (i.e. the inch-to-foot scale).
I don't think people critiquing USC are unaware of what this video is saying. We just think it's still worse.
