I was always wondering, in warhammer40k universe, what kind of technology is used by civilian populace. I mean they have TV, computers, cars, home technics (dunno how to call it, here we say 'bela tehnika', things like fridge, kitchen range, etc.,..), work machines, transport ... As they live in future, it is expectable they to have very high tech stuff than we use today. But the current imperial arsenal doesn't really look that advanced, the houses still look very similar to today age, they use the same roads etc. How developed is the civilan technology in that universe for the human imperium?
