I just realized. The pokemon games, they don't take place in an alternate world. Oh no... They are our FUTURE!
The technology is just starting, but a few generations from now bionic implants will be the norm, and every child will be implanted with a basic suite of bionic enhancements that includes pokemon go as default software. The world's population will drastically decrease as people fall to the whims of darwin awards, walking into traffic, jumping over zoo fences....
Soon cars will become far less common. After all Go doesn't really work while driving, big car companies will mostly go out of business and major roads and highways will eventually become overgrown from a combination of maintenance workers being too buzy playing pokemon go to fix them, and no cars being on the road anyway. And real animals, having being found to be a threat to humans during our treks into the woods to find fake animals will largely be exterminated for public safety.
Soon people who realize that pokemon are not real and are only part of augmented reality will be the vast minority, and seen as mad and ostracized from society. Wars will be fought with pokemon, as after all, for 'some reason' humans are unable to harm pokemon directly, but the tactile sense systems built into our bodies when we are young will let us feel the pokemon as if they are real, giving us the fear that they can harm us.
Soon we will have an entire world of pokemon. A world where children are sent out into a world devoid of harmful life, but full of illusionary life. And where nobody knows where pokemon eggs come from. Simply because the game doesn't show anyone.
