This. I'm eagerly awaiting the replicators that will explore the cosmos and spread the knowledge of our existence. If we can get them done before we poison ourselves.

You assume that we are the thing being replicated.

Nature is crafty. It could be the case that we humans are the replicators, not the main show.

You mean as long as they can run doom, or create a pocket universe that simulates doom.

And they'll be able to run Doom too.
