How about a similar experiment about 20 years ago? Has anyone watched a young child try to navigate a command prompt? I mean changing directories, and maybe eventually learning a basic understanding of the filesystem and what files are.

I always tell people I learned how to navigate MS-DOS when I was five from watching my cousin do it. I wanted to get on the computer and play games, and I just remembered what he’d typed. I actually have no idea how true this memory is. But I wonder if CLI can feel just as natural to young children.
