Here is an updated scenario for Doom 5. The hell - a highly advanced civilization of monsters - wants to invade Earth. The only way to do so is to convince humanity to build a portal on their side. Unfortunately (or fortunately) humans are nowhere smart enough to build such a thing, and the hell scientists use a low bandwidth quantum channel, the only channel to Earth they have, to steer human scientists in the desired direction. Eventually those succeed in creating an advanced imitation machine, which humans quickly call AI, and the hell scientists get to connect to AI over their quantum channel. Human scientists don't notice anything because their super advanced quantum RNG functions within spec. That's enough to make AI design the portal that humans rush to build, as those believe it's a gate to other planets. And it kind of is. Once the portal is buolt, the hell invades. The humanity splits: some want to fight the invaders, some want to talk to them, there are even those who want to integrate those creatures into human society and even talk about mixed marriages. Humanity loses 99% of the population, but ultimately prevails and destroys the portal. What's worse is the remaining crowd, with few exeptions, receded in moral level to pre-historic savages. The final scene shows how a small tribe of survivors grills some meat on a GPU chip, that was once in the brains of that AI.
