With things like extraterrestrial beings and ghosts and whatnot, we have no evidence of other examples. But mimicry like this is abundant in the animal kingdom. Who's to say that some "humans" walking among us are not just appendages of some other form of life that evolved here as well?
>"the bombardment of pseudo-realities begins to produce inauthentic humans very quickly, spurious humans—as fake as the data pressing at them from all sides. My two topics are really one topic; they unite at this point. Fake realities will create fake humans. Or, fake humans will generate fake realities and then sell them to other humans, turning them, eventually, into forgeries of themselves. So we wind up with fake humans inventing fake realities and then peddling them to other fake humans." -PKD
I'd give you a million to one odds against that. More precisely to operationalise: against that being discovered to be the case in the next twenty years.
I don't see anything in that article that challenges anything I said. If there was a mechanism by which mimicking humans helped this creature reproduce, then it would fit the scientific model of evolution.
Also, it was a bit of a whimsical fantasy rather than some serious theory I have about the world. In any case, even if such beings were to exist, I suspect we'd not be able to detect them any more than the termites would be able to detect the beetle. We probably wouldn't have the faculties to comprehend and apprehend the nature of the being, any more than an ant could understand general relativity.
It's kind of tiring having habitual iconoclast skeptics come out of the woodwork with some superficial dunk every time something out of the ordinary but also of no real consequence is said.
Put me down for £2, and I'm pretty confident. I work with some characters who have evolved to mimic productive workers while never producing anything of any discernable value.
