I think not everyone needs to know how their device works. Specialization is what advances us as humans after all. If they wanted to know, good for them, and if they don’t also good for them. If I were using a car, I don’t need to know how the engine convert a chemical energy, transfer power, and generate thrust
Edit just to give an example, an office worker may only need to use a word processor and their OS be up to date. If the user can just click the GUI to update the OS rather than typing the command for whatever package manager the OS uses, it is good enough for him. Sysadmin can give them the instruction once and done.
If the user forgot the instruction, they can explore it on their own with GUI without internet since no matter how deep a GUI config is, then there must be a way to get there (assuming the UI designer isn’t shit). Contrast that with CLI where if you forgot or don’t know any command there is little help or indicator of what’s available and what can be done without external help.
