Today our daughter and two grandsons were sitting on the deck looking out over the small lake they live on. It was a calm and sunny day. Out of nowhere a waterspout appeared, gathered strength and ripped the roof from their neighbour’s gazebo. They hardly had time to rush into the house when it had gone.
A black swan is a term for an event which comes out of nowhere and upsets everyone’s applecart. The last black swan was probably the day two planes flew into the World Trade Center. That changed our world. Now we’re living in another one.
