Trust me, plenty of millionaires are doing their laundry in a shared Waschküche in Zürich!
Current Chinese dev bots cost like $15k. Vapourware startups are claiming they'll ship their humanoid robot product at $20k. I'd pay that in a heartbeat for robot that could actually do my laundry.
(But more impactfully surely there are loads of Californians with a utility room in their garage, or a basement that can't be accessed from inside the house)
(Also... I just realised, if there were robots that could do laundry, but couldn't navigate to my basement, I would move. I think laundry bots would genuinely be that desirable)
The companies servicing that echelon would replace staff as soon as they could. In an apartment, the building owner would plant one in the shared laundry and add an optional price for tenants to use it.
The poorer will get robotics as a condiment. Like WiFi.
