Just picturing an alien archaeologist “so, as they stopped being crippled by polio or losing their lives building railroads, they complained about having to wash the dishes?”
Any alien archaeologist worth their preferred home planet’s seasoning ingredient would treat the development of a motorized sanitation device to clean large amounts of food prep and eating tools as a major labor saving milestone of technological development.
Thus complaining about having to the dishes is probably considered a reliable indicator of saturation of these devices.
This is why complaining about having to do the dishes is actually a selfless act of historical preservation for future alien archaeologists.
