The case I have in mind: cleaning hotel rooms. Build me a robot that can clean the toilet, change the sheets, replace the soap, check the mini-fridge, and do it all without breaking people's stuff scattered around the room. This is minimum-wage work which probably costs you $30,000 a year (including taxes, benefits, etc.) A $100,000 robot would replace that cost in just over three years -- one year, if it could work 24 hours a day instead of 8. That seems a huge ask. The tasks are all simple, but currently require AI-complete levels of perception, especially if combined into one machine. I doubt that a specialized robot -- or a series of them -- is likely to be cost-effective. Currently, they don't even use roombas.
