Complex is different. Inputs in a complex situation move. They dance with their environment in a way that changes them both. The ‘dance’ that emerges is a new entity, reliant upon, but independent of, its elements. Changes in its elements change it, and changes in it change the elements. Potential outputs span a range. Tracing a line from one side to the other with any confidence is a predictor only of the idiocy of the person doing it. You may begin at A, but you could end up at B, C, D, or Z, by one of an infinite number of paths. Complex therefore compels focusing on the journey, and the course correction, not the destination. It’s not a recipe, but a nutrition plan for a human.
