Assuming people to act rationally can really bite you hard. Life experience has taught that people are mostly irrational beings with occasional rational episodes.
I get that but to assume a board of very smart, competent people would just up and fire a highly respected CEO for no reason when it seemed like they were destined to be enormously successful and right after a well received keynote seems strange to me when it’s the least likely scenario if you just consider the facts that we all know to be true.
