The Culture series, by Iain M. Banks, represents a blend in which a transhuman society is guarded by godlike machine intelligences. A stronger example is posited in the novel Singularity Sky by Charles Stross, in which a future artificial intelligence is capable of changing events even in its own past, and takes strong measures to prevent any other entity from taking advantage of similar capabilities. Another example appears in the popular online novella The Metamorphosis of Prime Intellect in which an advanced artificial intelligence uses its own advanced quantum brain to resolve discrepancies in physics theories and develop a unified field theory which gives it absolute control over reality, in a take on philosophical digitalism.
