So, someone who is fluent enough in English that they would use a colloquialism like “killed the argument” somehow doesn’t know the difference between “roommate and house maid”?

And, even if you make that swap, who is making a “need a house maid” argument? Is there anybody who argues (with whom?) that they need a house maid because making a bed is too difficult? Yes, a maid might make a bed, but the bigger service they provide is cleaning: laundry, dishes, vacuuming, mopping, dusting, scrubbing the bath / shower, cleaning the toilet. A live-in housekeeper will probably also cook meals and do some childcare too.

A robot might be able to do some of that, but a robot that capable will be tens or hundreds of thousands. You’re not going to save money by switching to a robot.
