For semiconductor companies, it is Moore' law (transistor count doubles for every 2 years). For pharmaceutical companies, it is Eroom's law (drug approved decreases by half for every 9 years). One of the reasons for Eroom's law: Pharmaceutical companies depend on the newfangled target-based genomics rather than the old-fashioned and laborious trial-and-error method.
