Why was the Singularity removed?

[Frank_Stein]

the singularity was pretty boring

it had three states, "not on", "working fine", and "welp call the shuttle"

I think that was the main problem. If it was ever brought back, it would need more variables in between. Like, if it's power output was directly proportional to it's size/stability. If you wanted to keep everything on the station running at 100% power levels, you'd run the risk of it breaking free. Otherwise, Engineers/AI would strategically power down certain areas/equipment of the station where excess power wasn't needed.
