What is ending is not business with human workers but rather brick and mortar store fronts for items easily sold on the internet. Every internet business is inside a building somewhere, it's just not a store front. And there are human(s) working inside.
Brick and mortar store front business will persist for things that are best bought in person; cars, restaurant dining (not everyone wants takeout),large items of furniture that are best examined in person (beds, sofas), things that need to be examined in person for quality (antiques- not everybody trust an ebay photo).
Amazon is putting bookstores out of business but is still a business with buildings and lots of human employees. They just all work in warehouses instead of stores.
