Hear me out, bros.
I don’t mean that niggers will build doomsday machine or grey goo. They are obviously incapable of that, although they could steal or purchase the technology.
More likely though, on any planet with an intelligent species, a faster breeding but less intelligent subspecies takes over and eventually crowds them out. I think with all this Fermi Paradox stuff we take for granted that any human-like intelligence should evolve to be space faring. But I don’t think that’s the case. Although niggers are human-like, I could see them running the planet for tens of thousands of years of stagnation before decline, all the while never leaving earths gravity.
What do you think? Are niggers or nigger-like species the true Great Filter?
