Well, if you know that audience its cool. I was never afraid of the CLI, it was more that I could not find good use-cases and therefore stuck with the GUI tools, even when I knew how to use cd, touch, mkdir, mv, cp, ls, etc. I think the biggest break-through was when I was starting to write scripts as it taught me the rather complex syntax of conditions and loops (complex because whitespace is so important), but I would agree that scripts are a bigger beast. I think people who try the CLI but are not shown the true power of the CLI will eventually return to their GUI tools as they don't have to remember strange commands and read long man pages.
