The business case for humanoid robots is simple... for lack of a better term, they're robot slaves. Companies or governments can buy them once, pay relatively minimal maintenance fees, and have an army of workers that don't need a salary, never take breaks, never complain, never unionize, and do things faster and more accurately than most humans ever will. Any company that can move to robots, will move to robots.

Imagine the profits companies will have when they can eliminate, or drastically reduce, their single largest expense... payroll. Not only the base pay, but 401K match, insurance, payroll taxes, etc. Poof... gone.
