My mother used to have an early "digital company" back in the 90s in Argentina. We are from a small town in the "Patagonia region"[0] and there was only 1 programmer in the whole town. The guy was a huge nerd that had spent some time studying in Buenos Aires.
Long story short, my mother hired this kid to build software for him. This is around 1992 so it was all DOS.
This guy built a full TUI software with CRUD operation, reporting, "cron jobs" (some stuff that I never understood but would run every night), printing, etc.
Until this day I remember the people working at my mother's company how they just FLEW over the software. It was all keyboard and hotkeys. They'd just go back and forth, print stuff, enter data, connect with the Fax machine, all with their keyboard in this black screen full of green, white and orange glyphs.
I NEVER found any other software that is SO powerful and efficient and user friendly as TUIs.
