George Siemens discusses how learning will change by 2020. He predicts that there will be over 1 billion more people in a globalized, integrated world facing issues like climate change and resource scarcity. Technologies will transform learning through tools that make everything traceable, recordable, and integrated physically and virtually. Learning in 2020 will be adaptive, contextual, and aggregation-driven using networks rather than traditional institutions. Learners and course design will change to handle the complexity of issues through human-machine learning and matching systems to society's needs.
