The Year: 2525. The Place: Earth.
Our planet’s population has continued to grow, while our ability to live on other planets has not. With over 38 billion inhabitants, Earth has become more crowded than the average clown car. All those people needed somewhere to live, so every available inch of the world has been converted to living space. This leaves humanity with quite a conundrum: where will all our stuff come from?
Luckily, though humans are unable to live on other planets, we can quickly and easily travel to them via teleportation and stay there for up to 18 hours at a time, depending on the planet. Everyone on Earth with a job works on another planet, kids go to school on other planets, and all our stuff comes from other planets that have been scientifically adapted by us crafty homo sapiens to produce the things we need.
On Planet B-32, toothbrushes grown right out of the ground like grass. We no longer need cows for our milk, because Planet A&D is naught but a vast, constantly regenerating sea of homogenized skim. Planet 9V has been converted to a living lithium ion battery manufacturer, where batteries of all shapes and sizes just grow on trees, ready to be plucked…
At least, that’s the future as I see it. Is it perfect? Absolutely not. Is it pure science fiction, an unattainable notion that could never come to fruition? Probably. But it would be a heck of a lot more fun than: A) going to a store to buy a toothbrush, gallon of milk, or batteries; or, B) buying any of those items online.
Plus, after a few hundred years, after the expense of altering the individual planets had been mitigated by selling the individual items, the planet-produced stuff would become cheaper and cheaper, and, eventually, free.
Of course, since everything would be made automagically by planets that are essentially living factories, very few people would need to have jobs. This would inevitably lead to ever-faster population increases (because what do you think are people gonna do if they don’t have to go to work *a-wink*). In turn, this would require more and more alien planets to be terraformed into battery or toothbrush or milk or whatever generators, which would require workers, which would give people “something else” to do, which would thereby slow the population increase considerably. Ultimately, a stasis would be achieved, things would level off for a bit, and the whole cycle would begin again…
Sorry to go all Stanislaw Lem-y there. I just really hate having to buy batteries for my wireless mouse.
