Imagine being a human who born 30 years ago on a Tau world which has just been "re-liberated" by the Imperium, and after the whole thing settles down you are assigned to work in the Administratum, and this is you new work computer, sorry "cogitator", for the rest of your life.
Any wonder so many people revolt all the time, just look at that fucking thing man, there's dead people in it. Imagine there was a few dead people in your workstation, you would think you are losing your fucking mind.
