In April 1956, Popular Science told readers how to modernize homes with bleeding-edge technology. The mark of a great home, we noted, "is not its size or shape or color, but how much up-to-date machinery it has to make living easier." At the time, that meant retractable electrical cords, smokeless ovens, and countertop blenders. Today, that means something entirely different: app-based security systems, voice-controlled lighting, and cloud-based intelligence that learns your daily routine and adjusts the heat or AC to your liking--before you even walk in the door.
