Sometimes you want more than text. This is one of the interesting divides these days - and I say this as someone who spends a lot of time in the terminal. Computer interfaces and interaction did not peak with the VT-100. Sometimes, there is a very legitimate need to show tables, graphics, interesting graphs, and to use colour and shade to draw the eye and lead someone through an experience.
This is why I use an IDE instead of a TUI agent... I'm on a computer with a multi-megapixel display, I want to use it. If I could be driving the same process with my Macintosh SE as a serial terminal, what the hell is the point of my recent Macbook?
