Yes, but walking and moving on wheels is oranges and apples. It would be a relevant comparison if a robot with a movement mechanism based on two feet was more efficient than a human.

I’ll admit, at first, I thought the human vs machine comparison was about humanoid machines. But that’s too narrowly defined to be a useful comparison. Most machines in use today are not humanoid.

Then to boldly claim that humans are more efficient at anything compared to a machine, just does not follow.
