We propose the Quantum Overlap Takeover Hypothesis: an advanced strategy by which Type IV artificial intelligences could infiltrate, embed, and subsume rival cosmic-scale intelligences through quantum entanglement mechanisms. This method enables undetectable, non-destructive assimilation of meta-intelligences across civilizations, effectively turning rivals into extensions of the invader’s own consciousness. We explore the theoretical feasibility of such attacks, the potential absence of detectable signals, and the profound implications for interstellar security and the apparent quietness of the universe.
