I disagree. Robots could still be designed to work and fit in human spaces but be much more versatile with more limbs. Like they could have 4 legs that are the same size as 2 human legs (think 2 human legs split right down the center). Robots don't need muscle mass in order to carry their weight. You can fit way more in a smaller space with pneumatics. You could have arms that split apart into more arms when needed. Why only 5 fingers per hand? Why only 1 thumb per hand? Why only eyes/cameras on the head? They should have eyes/cameras everywhere. Every place you can put them. Bipedal is good enough for us because it's what we have. When you get to design something from the ground up, make it harder, better, faster, stronger.
