Ask HN: Looking for a sci-fi short story posted here

I've been digging around for a short story that I read that was posted here sometime in the past year or so.

In the story, some kind of deep future researcher finds an intelligence stored in a vast archive and plugs it into a humanoid terminal to hear its story. The intelligence was originally a human which was trained to mentally control multiple points of awareness simultaneously. They have their consciousness transitioned (or copied) to silicon and are used for various purposes, including controlling production lines at a factory. Eventually, they start to be used to control fleets of military spacecraft. For whatever reason, the intelligence is decommissioned and stored away to be found much later by the entity at the beginning of the story.

Hoping this rings a bell for someone, it was a great story that I'd like to share with a friend.
