Too many people just shrug, or even laugh, when they hear that a smart homes/Internet Of Things service has shut down overnight. They even use the word “service” without really understanding it. Many, many people in that field don’t really want to have to handle customers; “customer” being the word for human beings who have expressed trust in your expertise and conscientiousness using their own money. Many of them have never done time in retail, and learned the principles of delighting the customer, nor utilities, where you will never hear from a customer until something goes wrong and the victory condition is silence. There’s no dopamine hit in utilities. Don’t do utilities if you want to be loved. Don’t do retail if you can’t handle having the insanity of the human race rubbed in your face every day.
