This guys a good forward thinker, I mean seriously the tau are the only ones making actual progress forward I mean if their development of tech is exponential (which it sure seems to be seeing as they went from primitives mastering fire to a race more advanced then the Empire in 6000 years, it would have to be.) their gonna have tech more advanced then the Eldar in 1000/1500 years tops, the Empires kinda fucked.
And those people will burn in hell because they followed a false God this whole time! The Emperor is just a decaying corps, on a pimped out throne, and he just happens to have super-powers. That does not make him God!
