Today I was thinking about the slightly silly suggestion that Amazon would soon have a swarm of robot drones zipping about some city delivering stuff to customers, and the first thing that came to mind was - why Amazon? Don't they sell mostly books, and they're going increasingly digital? In fact, I thought, in 100 years time, all human needs will be covered by digital delivery, with the possible exception of food and water. [But even then, perhaps people will buy a lifetime supply of several tonnes of powdered protein and nutrients and have their 3D food printer arrange it into something different and tasty every night. As for clothes, it will be so hot that everyone will be a nudist, but even if needed for a special occasion, the 3D printer can probably deal with that too. Perhaps using some of the starches that can be used for food. My semi-dystopian nude future is efficient, solar powered, and waste free.]
As for human companionship, well, half of that is already over the internet, it seems, and it's a wonder there's not some groin clutching device available already that allows telepresence to deal with the baser instincts. Some scientific team in Japan is probably already working on it as I write.
So, in my (already creepy) vision of digital isolation, what's left that flying drones would still need to carry? Well, um, carrying on with the matter referred to in the last paragraph, they could play a role in reproduction. Do I need to spell it out? In fact, male "donations" can already be shipped directly to a person's home (check out this lesbian owned business's website) in the US, if not other countries; and the only innovation in my weird future is that it's delivered via a buzzing drone passing overhead.
[In many respects, the present era of reproduction day is way, way stranger already than people imagined would ever be socially acceptable even when I was a child. Exhibit 1: Elton John and his partner having two kids and not knowing which is the father? And this is covered in non judgemental fashion on the cover of celebrity magazines? I'm having strange thoughts about airborne gametes here, making human society resemble coral spawning, but it's only a minor elevation of the oddity of the present day. ]
But going back to drones: it's not a big stretch to imagine that frozen embryos might be delivered to your home this way in future. [Where they can be raised in a RoboWomb with a clear plastic window that makes monitoring progress easy. Spray on bacteria for when baby is decanted will be important, though.]
Isn't this a great explanation for the myth that babies are delivered by storks?: it's a premonition of the future!
