Why would I need a developer when I can build everything for my app WYSIWYG in Visual Studio? Why would I need someone who specializes in databases when I can just build it in Access? Why can't we just build our site in squarespace and not have any resources at all? There's always something that is supposed to come around and replace engineers but it never comes to fruition. These attempts are good to build shallow products and MVPs. For "vibe" coding, the product will not be serviceable if the person who implements it does not understand what the code is doing. This is the equivalent of rote learning and expecting the implementer to be an expert
