One thing that's been really useful for many years is the Help menu in MacOS. You click it and start typing the command you are looking for, and MacOS conveniently opens the menu and any submenus and shows you the command with a big blue arrow. Wouldn't this be easy to pair with a simple AI, so that people can more freely type what they want to do? Maybe even make it Spotlight accessible.

I like the visual and thus get along much better with drag-and-drop than any text based interface. So for me (and maybe your mom) the best solution would be that Sally was a window you could open and drag things to. Surprised that Apple and nobody else ever did this on desktop. At least on iOS, your friends are pictures that appear whenever you press share, but it's not perfect.
