I experienced the same thing. The big Brokerage firm I worked for in the 90s had amazing TUIs. You could fly through the screens. They even had DMs and group chats. Pretty amazing. The next company I worked for was rolling-out a GUI replacement for their TUI interface and I watched people's productivity plummet as they went from keyboard, to mouse for every text box... Those old mainframe TUIs were amazing, probably the result of decades of time and motion studies.
