That is exactly the reason why I like the text interface so much. It makes you think about what you want to do next.
In a graphical environment, there are lots of hints right in front of you what you could do next (made even worse in other OSs that use pop-ups).
In a text environment, unless you actively do something, all you get is a blinking cursor.
It increases my productivity and reduces time wasted on the computer, not because it is a bit faster, but because I don’t get distracted.
Just wait till you hear how we pronounce “Chicago”.
