This document discusses the shift from prescribed personalized experiences to cooperative experiences where users have more control and agency. It provides examples of companies like McDonald's, Tinder, Valve and Uber giving users more options to customize their experiences. Emerging technologies like 5G and AR will enable more ubiquitous customization, but also increase the risk of overstepping user boundaries unless businesses emphasize personal agency and partner with users. The document advocates for businesses to better understand user trust, identify opportunities for more user control, invest in technologies that enable participation, and prepare for increased data regulation.
