I can assure you that most people now do not consider indoor plumbing, washing machines, and dish washers as big things.. but then consider what happens when there's no power or water for a week. While people have internet access through their phones, and can make business deals to the other side of the world, they can't operate the various home appliances which made life feel normal. These are the things which used to be done by servants and women of the household, back before there was home electricity.
