“There are all sorts of libraries and frameworks that are supposed to help you on your journey of writing a GUI, but despite all the best practices and frameworks forcing you to eat your vegetables, the GUI always ends up being a ridiculous mess.”
Every framework sells neat little boxes that don’t know about each other. Then the user avatar needs to change when the inventory table does, and the boxes have to talk. The mess was never the framework’s fault. It is the product. Users want everything connected, and isolation is a lie the architecture diagram tells.
