Marques Brownlee maintains that the human shape is not necessarily the most efficient form for a robot to perform tasks.

“it turns out the human shape for a robot isn't necessarily the best shape for a robot to actually do things.”

Specialized, single-task robots are preferable to humanoid robots because the humanoid form factor makes everything more difficult.

“I just never thought that the form factor of robotics needs to be humanoid. like it makes everything more difficult and I would rather I wish and I know I've lost this battle. I've given up. Everyone wants a humanoid robot. I rather would have a laundry folding robot in one corner of my house.”
