I suspect that the purchase, maintenance and software licence costs of an extremely complex piece of machinery with incredible AI isn't going to compare that favourably with a minimum wage human anyway, even spread out over a few years.

>McDonald's former CEO Ed Rensi: "It’s cheaper to buy a $35,000 robotic arm than it is to hire an employee who’s inefficient making $15 an hour bagging french fries."

As a householder, I don't need someone to bag chips for me 24/7. Having someone spend an hour cleaning my flat once a week would be quite useful. Unfortunately, the robot arm doesn't have enough moving parts or AI to do that, and even if it could, I could hire someone on a $15 minimum wage to do that on a weekly basis for 44 years for the same price as the robotic arm.

And if the hardware costs mean it's not a mass market product, the software licences aren't going to be cheap either.

Roomba etc can be cheap because the forces are small and required accuracy is low. An arm that can e.g. load a dishwasher or plug itself into an electrical socket is another beast. Consider that to lift 1kg payload the arm also has to lift itself, and arms typically weigh several kilograms.

Mass producing robots will help costs, but they will still be expensive like a car, not like a TV.
