Thinking about this today, one of my favorite electronics teachers (RIP) when I was in college told us to see what would be tomorrow's big technology all we had to do was look at today's children's toys. This was in the late '80s, he used the example of the transistor, how it started in children's dolls and simple electronic gizmos by the 50's, made it's mark in cheap transistor radios of the '60s, and eventually became the powerhouse and driving force of the current microprocessor and computer age. I would confirm this theory is also true considering LEDs, as they started out as mere indicators and lights in childrens toys in the '60's and those futuristic digital watches of the '70s and now are part of our HD lifestyles in everything from big screen tvs to our cell phones and IPads, and that's not even scratching the surface how they are used in industrial applications. So if there is any truth to this "Toy Theory", what is tomorrow's next big technology based on the toys of today? Your opinions, observations, and theories welcome!
