The United States National Security Agency (NSA) monitors, collects, and processes data from a number of sources world-wide for foreign intelligence and counter intelligence.

The simulation argument can be summarized as the idea that reality might be a virtual simulation (we might be “in the Matrix” / “in a video game”).
