Even today, only the superstar authors actually earn any decent money from their writing. You're absolutely right that we need to find a way to provide people food, shelter, and health care. It's true today and it will be true in the future. And it's true for everyone, not just superstar authors. Publishers will continue to have a role as curators of information, but they're going to have to change their business model. Instead of profiting through the sale and distribution of information, they'll have to earn money by selling their editing and curating services. Amazon will be fine. They'll always find products to sell. It just might not be books or movies or other forms of information. Edit: People already are less willing to put the work into creating great literature. Being a writer is not a reliable way to earn a living. Imagine how much creative potential we might unlock with something like a basic income.
