Summary.
The prevailing narrative in business today is one of ever faster change and creative destruction: Big Tech companies are taking over, the number of unicorns (start-ups worth $1 billion) keeps growing, the average tenure of old-economy companies on the S&P 500 is plummeting, and incumbency has never been worth less. The message to established firms—play catch-up or die—is bleak.
