This document discusses the evolution of design from the 19th to 21st centuries. In the 19th century, engineers exploited energy resources like coal to power industry for the minority. In the 20th century, marketers understood consumer desires to fuel mass production. Now in the 21st century, designers aim to empower individuals by creating simple, fair, and beautiful solutions through collaborative digital technologies. The document argues that designers must think differently by imagining user experiences first before developing technical solutions, in order to design a future where everything is connected through ubiquitous sensors and computing.
