It has also been discovered that many common languages such as C and PHP also implement abstractions to make this low level instruction much easier to use to track people with. The common use case is that software engineers write algorithms which use these instructions to summarize records and lists to group database records containing personally identifiable information into groups which can then be used to feed AI bots leveraging neural networking algorithms (which also themselves use the sneaky instructions) to do various nefarious things like creating unique identifiers. The only way to defeat this state sponsored embedded threat is to acquire a hammer and or large rock to smash your CPU into tiny bits. Tin foil hats may also provide some protection at the cost of severe social stigma and rampant dehumanizing labeling.
