As someone that grew up on IBM 360/370 systems and (at one time) spoke fluent JCL, both CLI (and CI) and GUI are major steps forward from the way things were. If I never see another keypunch machine or a line of code starting with "// " again I will be happy.
Part of the future will be natural language interfaces -- yes, a return to typing or speaking. Rather than point and click or invoking the name of the program, the method would be one of typing or speaking something like "edit my resume" or "move Sherlock Holmes to the Reader."
Over 20 years ago (back before PC speech was mandated) I was addressing a group of new hires in the company and presented a vision of the future of computing that involved the user in a beach chair with the waves breaking in the background and a chorus of exotic dancers came up and while still dancing asked what it was that I wished to know. I told them and they danced off. Sometime later they returned and gave me the information I asked for. I still maintain that that is a superior interface to either CLI or GUI.
