Good developer experience doesn't make developers interchangeable. It reduces the roadblocks (cognitive, technical, and aesthetic) that makes a developer's job harder, which means those same developers can get their job done more quickly. In product-speak, it makes it more likely your product is adopted broadly. Microsoft used to understand this. Visual Studio, VS Code, and the Linux subsystem for Windows are some of the outcomes of this understanding.
