In 100 years technology will grow to bring us colonies on Venus with houses hovering over the hot surface of Venus. There will be flying cars with probably a voice. Technology would become so powerful that people would be in floating chairs and be too fat to walk independently. Watch Disney Pixar's movie Wall-E for insporation. We would be cyborgs if our body parts didn't work correctly. Phones might even be transparent. Alexa might have another friend besides Siri. People wouldn't be memorizing things anythings anymore, because technology would have told everything and that is what we would rely on. Technology would have become are favorite thing in the world. Cat lovers would be robo-cat lovers. Most things would be electric or solar-powered. Books might not even be a thing in the future.
