Sure, but those are incremental gains rather than some sea change. And for the most part that market already exists. The problem is those things have no easy answers. From the list the only thing I can see is some sort of decluttering robot that picked up and put away all the scattered toys, so robot vacuuming could be done. Maybe some kind of integrated laundry machine that did washing and drying in the same space, then a conveyor that sorted/folded/stacked clothes? Those would be helpful, but would ultimately just end up as another "buy this expensive gizmo also, to make your life slightly easier"
