The author makes the argument that because Tim Cook does not demo new products, Apple is incapable of innovating, and is just cruising on the goodwill of the brand.
What a crock. Tim Cook is no Steve Jobs, and Apple is most definitely different without Steve. But, under Cook the following has happened: Apple Watch, AirPods, HomePod, iPhone X, ARKit, Siri Shortcuts, FaceID, iMac Pro. Everything in that list might not perfectly suit every user, but the argument "Without Steve Apple can't innovate!" totally falls over.
Steve gets a lot of attention for his innate sixth sense for product, his masterful presentations, and more. But, I think this era of Apple proves that he was also great at creating a culture and ecosystem that can perpetuate without his presence.
