The system uses a command voice to infiltrate the organic collective consciousness and convince individuals to give over their decision making process to an engineered set of memes that build up over time and act as a literal form of brain washing to reprogram human behavior.
The command voice is most likely delivered through more than one method. Likely candidates of delivery are an international microwave network distributed via something like cell towers or electric power grid nodes that can induce a 'voice to skull' effect on a populace.
Likely candidates for targeting and removal are anti-corporate individuals, scientists/atheists, and general creative thought/artists, positive/confident intellectuals, and government workers/supporters.
The signal is designed to train people to actually give up control of their nervous system and thinking by instilling a mistrust of their own observations and opinions through harassment, negativity, isolation, and intimidation.
This phrase was first coined in the 1981 short story "Johnny Mnemonic" by William Gibson.
