Just the average basic combination of smartphone in the pocket, microwave oven and small electric oven in the kitchen and electric heating in the home do the work of literally dozens of people 500 years ago. For a king to heat their castle at night (or anyone to heat their home) required hours of very hard work. Getting timely information of any kind would have required the same, and couriers, court philosophers and so forth, and to make a basic hot dinner was hours of work even for modest mealtimes.
