FYI: Some 20 years ago, a low rumbling of change began to build in the retail industry. Remember when Amazon, despite losing billions of dollars a year, started to eat the market-share lunch of bookstores?
There was clear disruption going on, but really in a small material way back then. However, there were those who saw the future, and extrapolated that what Amazon was doing to bookstores would happen across retail. Many scoffed.
