[MASSIVE PLOT SPOILER DISCUSSION] - WAU

[Darth Biomech]

The ARK ensures that everyone who was scanned is allowed to live on. Destroying WAU ensures that its experiments stop and some manner of the natural life on Earth is preserved without being mutated so that eventually something new may evolve from the ashes untouched. There is no reason to leave the WAU. It is a wide-spreading and uncontrollable AI set on desecrating the corpse of the human race - quite literally.

The ARK is a joke. It is futile. All it do is prolonging the life of those who uploaded on it, but it is just a solar powered computer in orbit around the sun. People in it cannot evolve, cannot return to physical world, they cannot even repair their satellite if it start breaking down! I think people who build it didn't realized that in same way that Simon didn't realized that he will be left behind.

WAU on the other hand is whole other thing. It can interact with physical world. It can shape it. It is trying to figure out the correct way of restoring humanity, and it is almost founded it - Catherine acts and sounds like a normal human, so is Simon. Eventually humanity will be able to rise from ashes in posthuman mechanic bodies. And there is NO "natural life" on earth is left. Yes, there is some weeds, and fishes, and life on the ocean floor... But all of this is depending on the nutrients provided from the corpses that sink from above. and all THAT was killed by the comet impact. Life on the land is also COMPLETELY destroyed - ENTIRE CONTINENTS burning so brightly that it is visible from orbit. So killing WAU is not a right thing, it essentially is destroying the only chance that intelligent life on this planet could reinstate itself. I'm afraid that Earth won't be able to sustain organic-friendly conditions for another 4 billion years to let life evolve again from bacterias.

I wont even comment on the "desecrating" BS.
