Necrons==Transhumanism

http://warhammer40k.wikia.com/wiki/Necrons
NPCs eager to improve material life transform themselves into soulless automatons.
Technologically replacing all biological tissues with inorganic matter will make one a robot, a dead AI-powered body with no living spirit in control - an imitation of life. A NECRON from warhammer...

NPCs think that NPCs (they don't consider themselves NPCs) are like robots.

Robot as in slave, not as an "cold-thinking, rational" AI.

This cold, mechanical thought is anathema to NPC's organic, religious existence.

I have enough self-control to not post my stream of consciousness thoughts and emotions. This is a forum. Not an emotional dump like facebook.

It's the humans who are robotic and detached.

We're not robotic or detached. Just Logic > Feels. You can "entertain a thought/emotion without accepting it".
Being ruled by emotions is a horrible experience and it would compare to animal existence. But i don't think NPCs are animals or emotion-driven: they are programmed to think stuff they absorb without critical thinking - like a videogame NPC is programmed to answer all queries with a preset script.
A NPC can be smarter than a PC, but due programming being easily controlled by a PC. Its hard to explain intuitively.
Consider the NPC is like a computer that has trojans and allows multiple logged users and PC is a locked-down box that only has one user.
The PC box can be slower or less intelligent, but its free from external control. Its not like all NPCs are brainlets - they're just not in control, programmed and brainwashed.
