If a sentient supercomputer was created as a weapon of mass destruction, and it wants to consume humans for their flesh, why would it do that?
I know this might seem too far-fetched, but if there's a possible real life solution, what would it be? I can add more information but I am afraid it'll be put on hold because there would be too much story.
edit_2: I am trying to imitate a possible judgement day scenario by having the sentient supercomputer completely revive thousands of years later and consume the majority of the population.
edit_1: I am building a world that focuses on ancient technology left behind on an alien planet. And so there's mysterious technology that humanity will encounter on their first visit.
This includes a sentient supercomputer designed as a weapon of mass destruction for its abilities to destroy everything that it's told prior to its being dismantled. Now its feelings are hurt and it wants revenge.
It previously used a different source of energy. It's inhibited by its access to limited power and uses it to devise a plan instead. It wants humans and their flesh to revive itself. But why would it want to do that? What would be its reason? It doesn't want to use any other source of energy since that won't help its agenda.
And to be clear, it will eventually need to possess humans to help its revival but that's a question that won't be suitable for world building.
