It's the summer of 2075, well it would be if it wasn't always summer. Things have changed, we used to have seasons, spring, summer, fall, and winter, but not anymore. We have a climatizor covering the Earth and every other planet we inhabit.
Sorry I think I rushed into this a bit too much. Let me explain from the start, back when I was 15 I had come up with an idea, well I didn't come up with it, but I designed it and finished it up. I was experimenting with some Vibranium trying to use it for the shell of an Android program. It went wrong, in a good way some said. To me, it was bad, the metal had mixed with the programming and started making buildings, small tiny building about the size of a fingernail.
That's where it started, now our planet is full of it, so many people were put out of work, as well as companies. Everywhere you look is a skyscraper made out of the stuff, no actually natural building materials except some concrete here and there.
Just a fictional story that I thought about a little bit and threw together, hope you enjoyed it.
Books/Movies that inspired me and gave me ideas: The Giver, The Hunger Games, The Divergent Series and Tomorrowland.
