Hey thanks for the response. Of course it's for the target audience, which was my overall message. The person I was responding to was arguing that people in general should know how an OS works, which is complete nonsense.
Rereading my response, I don't think that's at all what I was arguing for. I thought I was quite clear in qualifying the specific situation when I thought it would be helpful to know about lower level details. I'm sorry you interpreted it the way you did.
