This document discusses the concept of software defined decision making and its potential impacts. It envisions a future where sensors collect data from things in the physical world and analytics are used to simulate outcomes and refine decisions made by actuators. This closes the loop between observation, decision making, and action. It could allow applying artificial intelligence and automation at massive scale across many domains. The document also discusses how this paradigm, combined with technologies like cloud computing, could transform businesses and the types of applications and services they provide.
