If writing a GUI was as easy and stable as writing a TUI, yeah we should write more GUIs. I can run practically any ancient TUI program on a terminal emulator, but running a GUI program that uses an older version of GTK means going through dependency hell to compile and install all the old library versions. If they even compile with the new GCC... I really wish we had a standard way to spawn a webview (or similar) and connect stdin/out to it.
