The market exists, does it make financial sense to fill it? Are there enough johnfns out there willing to buy enough of them at high enough of a price to justify the mind-boggling capital required, not to mention the opportunity cost?

If you make a $10,000 robot that can do all of the dishes every damned household with kids in any semi-rich country will get one. A very good portion of our night is spent cleaning up after supper with just two kids, and that's time we can't spend with them. I'd even pay a subscription on top of that $10,000.

If it does laundry too? We'd easily pay $20,000, and we don't have FAANG type salaries.
