In typical fashion I woke up this morning with an interesting thought; what if an alien race appeared and brought us a gift of technology, something such as teleportation. What if it wasn’t a gift but a crashed ship and the only thing remaining were two teleportation chambers. Scientists would have just enough technological know-how to replicate them, all the time patting themselves on the back for being so clever. Humanity would trip over themselves to put teleportation devices on every corner of the world. We would likely do this without fully understanding how it worked. Sure teleportation would be amazing but it would likely take us several decades to fully understand how it worked, if ever. But what if this “gift” were in fact a Trojan horse of the worst kind. Imagine every time you use the device the alien race were replacing a few atoms with their own. Ever so gradually we would start becoming like them. This change, gradually introduced over time, might be so slow it would be chocked up to some quirk in evolution.
