Surveillance is gathering and recording information for processing and/or analysis.
Amplified by technology, the accumulation and processing escapes comprehensible proportions.
There is no such thing as Artificial Intelligence in the literal sense: machines organize information, they don't think creatively. Augmented intelligence is more accurate. Regardless, the term signifies the filtering and arranging of information at superhuman levels of efficiency.
Big Data unites surveillance and AI: Information of all types is gathered on scales, and organized at speeds overwhelming human abilities.
Individuals are incapable of comprehending big data, and therefore unable to out-maneuver it.
