Back to the Future II is an interesting case study in futurism in film, but it’s also a fun way of looking at our expectations of where technology was going to go. In 1989, we thought there was a good chance we’d be on hoverboards and flying cars powered by our waste products. Who could have predicted Nike would file a patent for self-lacing shoes?
Sci-fi drives our passion for technology and the innovations we make in real life. We jokingly talk about home surveillance like a throwback to Big Brother in the book 1984. Today, home monitoring systems are common and safe. The entire smart home is something our grandparents never saw coming, but they actually did have some equivalents back then that might surprise you.
Door Shakers and Home Security
Post World War I, theft became a major issue as folks struggled to protect property. Americans realized home security was a challenge, and that one needed to work hard to protect what one had earned. Burglar alarms were sold that would create loud noises in the event of a break in, but the door itself remained a weak point in home security.
Enter “door shakers”.
