Someone mentioned a scifi short story with link to online version that I followed & read. The story was about a uploaded-human AI-spaceship that for a time worked as a asteroid miner. After a single overmind takes over 1st the inner planets, then the whole solar system, the protagonist to flee to insterstellar space, but is pursued by an overmind ship.
Been trying to find the story/title/author since, with no success.
