I highly doubt that. These are people who have essentially never used a keyboard to do anything but type messages. If they can't type in a URL, I doubt they'll be able handle a terminal. All the younger people I know just click icons. Even if they want to move something, they drag-and-drop. No one's heard of cutting or file extensions or knows the layout of a file system. They would understand zero parts of `mv ~/Downloads/photo.jpg ~/Pictures/photo.jpg`.

The only way that would work is if your CLI is just a pipe to an improved version of Google Assistant or Siri that can generously understand natural language.
