This is proper use of robots. Repetitive work that is error-prone for humans to do.
Also, notice the robot is not in a human form, because it doesn't need all of that overhead. Imagine Elon showing up with one of his robots...
"Why are you trying to sell me a machine that can dance the Charleston and do backflips? I don't need that capability and I don't want to pay for it. I don't even need a robot that can roll, let alone walk and dance."
