Or is it SyFy?  Anyhoo, one of my favorite comic sites, Dresdan Codak,has produced some hilarious vignettes showing what caveman science fiction would look like, assuming they copied the predominant conventions of modern science fiction to both deride technology as ultimately evil and humanity's attempt to mold nature to our will with our extra-handy opposable thumbs as ultimately doomed.  DOOMED!  But before it was ok.  Cause we hadn't gotten as far, because it was before.  You know.  Got to know your limits.

Like really sharp rocks.  I knew flint knapping would be the end of us.
