Command line is no longer used by the general population because GUI is a far better user experience.
Code has nothing to do with command line vs GUI.
You don't need to interact with code to have it effect a users experience, a users experience does not have to be interactive, for instance: is an app or site that runs below 60fps or has networking problems good for the users experience? No. you fix this with writing good code.
