Isn't it heavily implied that artificial intelligence rose up and to defeat it humanity pretty much lost everything, leading to the Age of Strife? I mean, in the Imperium they have specifically outlawed the creation of sentient androids and resort to Servitors and nobody knows why.
Also, the Imperium isn't just neo-feudal. They have different modes of production on different worlds. I'm sure there are technologically advanced worlds that have a communistic structure. Planetary governors are allowed to run their planets as they see fit, as long as they adhere to the Emperor.
>Basically it’s fantasy with all the reactionary baggage that involves.
I mean, the entire portrayal of the Imperium is so over-the-top ridiculous, I feel like it was originally designed to be satire, like Starship Troopers. It's just that retarded /pol/tards can't tell when they are consuming satire, so they think it's some real shit. Also, the Tau are not bad, are they?
