SysOp
From the SL4 Lexicon:
SysOp:
A human or AI-derived superintelligence serving as an "operating system" for all the matter in the Solar System or beyond. A living peace treaty with the power to enforce itself. A Friendly Superintelligence ready to do whatever the "inhabitants" ask - including upgrading us to superintelligence ourselves - so long as it doesn't violate the citizenship rules derived from Friendliness. (For example, asking the SysOp to kill someone else, or to use more than your share of the Solar System's resources, or even to upload and upgrade someone against their will.) One of the possible outcomes of the Singularity; see Interlude: Of Transition Guides and SysOps Yudkowsky01. Sometimes called a "SysOp Scenario". A SysOp might be an agglomeration of superintelligences rather than a "single" one, and would certainly need to lack any selfishness or self-righteousness to fill its role appropriately (which probably wouldn't be too hard for a superintelligence to pull off; it looks like there's a good chance that even humans would be able to create selfless and non-self-righteous entities in the form of Friendly AIs.) See also Friendly AI, singleton.
A possible post Singularity scenario originally created by Eliezer Yudkowsky and discussed in CFAI.
In this scenario, after an AI creates the Singularity, an AI appears known as the SysOp that has overreaching control of the Singularity. In the case of a Friendly SysOp, everyone gets what they want unless it violates morality (including the ability to say no-thank-you to the SysOp and the Singularity).
