It's a discussion of reality stemming from an inspirational fiction. The whoosh apply to you.
Perhaps it's predecessor was just advanced enough to build self-modifying replicators and fire them out into space. Eventually it hits a planet or asteroid and gradually becomes sentient and intelligent. No trace of how it originated.
I personally hate that it implies there are faster ways to travel than light speed. We know this to be a hard limit in the physics of our universe and it rubs me the wrong way when SF writers just glaze over reality. Not to mention hydrogen life forms, what’s that about!?
