UPDATE: The point of this post is that we tend to worry about the things we can’t control and ignore the things we can. The best defense against any threat — known or unknown, established or emerging — is to make sure you’re always improving your game, optimizing what you can, when you can, so you can react when you need to. The example was Uber, which cab companies should have easily been able to neutralize early on. They didn’t, obviously, and have suffered. Data from this recent Fortune article shows just how dramatically.
