Yeah good point. Navigation can be unintuitive too. Like, how do you quit? Is it q? Ctrl+C? What even is the weird symbol before C? Those are some of the hurdles that must be overcome when coming to CLI and not necessarily easy to remember. Sure you can do it in 1 hour, but say tomorrow would you remember it again? What if the system is running smoothly for 1 month and you never opened the terminal again after those 1 hour?
