Feudalism didn't organize enough intelligent people and trick them into producing enough shit like plastic, nukes, etc. to eliminate all life on this planet. Forever. Soon.
We humans cannot eliminate all life on this planet. Even if we set that as an actual goal, we would fail. We can wipe out a lot, cause vast harm to existing ecosystems, but life will go on long after we make ourselves extinct.
And then a meteor strikes simultaneous to a sun blast that wipes out the air of all kind. This because the sun know better than to allow that dimension's access to our universe.
It is not and will never be intelligent. It will through random values at everything till it swallows all the mass of this whole solar system, galaxy and before long, the entire universe.
