That's my experience after years. Try it out and introduce in a lecture a command line when the audience are not people who know how to program.
The vast majority are "just users" who have to fulfill a given task as quick as possible. It is not about intelligence or ignorance.
I often compare it to a car. I "just drive" it, I don't care about its gearbox or motor setup. Machines that hide their internals are a success because even engineers sometimes just want to use things. When I compare Windows with Linux (I have a Manjaro installation on my laptop too) the main difference is in my eyes, that Windows offers you the "it just works" experience while Manjaro purposely lets you look into the internals, lets you install kernels etc. And people who like or want to look at internals choose not Windows as main OS when they can decide.
However, we drift away from the topic that FC 0.19.3 was released.
