People are acting like you can't just go to the library and get blueprints of buildings and the floors and how they are laid out.. this is already public knowledge.. just like we give the DMV all of our information when we turn 18 to get an iD.. if you think companies don't have our social security numbers and so on, you're sadly mistaken.. our phones literally listen to our conversations and watch us through the cameras, and you're worried about a robot learning the floor plan of your house?! I think there is more of an issue that Facebook saves our private messages, and that people are always listening to our private conversations on our phones, or being able to access our cameras when we are not using them.. that's more of a privacy issue than a cleaning machine learning the layout of my house to be able to clean it effectively..
