We are living in the middle of a crisis like none other that I've experienced in my life that's the essence of a complex system. The COVID-19 crisis is not a crisis; it's a health crisis; it's an economic crisis that was generated by the health crisis; it's a mental health crisis. In the US now, we have a racial equity crisis. By the way, none of these crises are new. The intersection of these things is part of the essence of the complex system. Each of them on their own are complex systems.
