We live in times of profound transformation, marked by a crisis of sustainability. A centuries-old modern industrial world is coming to an end and a new world is being born. Potential is everywhere, both bright and dark. This emerging world of the 21st century is complex, systemic, interconnected, ever-evolving. It requires new ways of thinking to take us from machines to ecosystems, from straight lines to circles, from hierarchies to networks, from competition to synergies. To see not just the parts, but to see the whole, not just analyzed but synthesized. Powered by systems thinking the problem-solver of the 21st century is both a creative thinker, and a critical thinker, understands the potential of ideas and technology, to remake our world. Think better. Think in systems.
