I'm making years of progress in minutes, developing tools for open source game development. Asset viewers, asset editors etc. ChatGPT can output a 3D model viewer in seconds when you tell it what API you want to use. My API of choice has been Gtkmm-3.0. I describe the UI I want, usually with a tree view or canvas view. Once I've defined the UI, I define what content I want in it and the system generates it. It is working incredibly well. I've also developed a working Audio control panel for GNUstep that seamlessly integrates into SystemPreferences.app and wrapping pipewire, next will be Network-Manager and and Wayland-randr/X11-Randr Control Panels for monitor setup. It's bringing the dream of a Mac-Like open source desktop closer to reality.
