Chang's Law (Semper Idem)

Chang's Law is the observation that infotech and biotech related technology advances exponentially. Named after Lane Chang, a history professor at Purdue University, who described it extensively in a 2028 study in the American Journal of Science. It became popularized within the computer science community, and was observed and verified with the "Tech Fever" of the 2040's and 2050's. It was also used to warn the populace about the upcoming threats of transhumanism by some experts.

However, similar to Moore's Law, Chang himself predicted that the Law would only last up to a certain point, after which exponential technological advancement would become too expensive or unnecessary to reach. Chang's Law describes the rapid technological, social, and economic changes the new technologies of the 21st century would bring, and the inability of many people and governments to deal with these changes. Generally, Chang's Law is not described as a natural or physical law, but a historical observation.

Effects
The revelation of Chang's Law would become influential in the creation of the Automation Safety Net Act (ANSA) in 2029, passed by the United States Congress to provide a welfare net to those put out of work by automation, as well as protective measures against automation and regulations against artificial intelligence. While the law was generally considered a failure, not able to prevent the Great Panic with the added downside of many infotech companies moving out the United States to more AI-friendly nations such as China or Japan, it was considered an important step for sheltering the population from the adverse effects of AI.
