the cost of labor is shared the the working class as well , it is not just tha capitalist class that pays for labor that labor cost is in the final cost of all the goods and services you use. These robots make life better, if you don't want to buy a robot that is your choice but do not take the freedom of others to buy ,use make and modify robots.
You're entirely missing the point. Unless you can build the robot in question and the infrastructure that supports it's ability to operate, you will never own one. You will be a renter of hardware and services and you will be subject to an externalized market controller who can—at will—arbitrarily raise the costs of operating said robot.
