We are going in circles here, your perspective is skewed because you are looking from a very distinct professional viewpoint. Whereas I recognize big "userbase" which wants linux just to "work", without "tinkering". You are never going to persuade those to learn the terminal in the way you described.

And again I am a long time user not versed in awk, regex etc. and I have minimal problems helping myself when in trouble with linux.

Basically your suggestions goes to far...

Thats all I am saying.
