I don't think the command line is an issue. I don't think instructing a user to open a terminal and issue commands is any harder than having them open regedit and add obscure keys.
The really sweet spot is a well designed GUI configuration utility which allows you to generate approriate command line scripts to allow the configuration to be duplicated. Unfortunately, this is rare in the Unix world and non-existent in Windows.
Compared to GUIs, command line interfaces are stable. I am still using commands for 20+ years ago to adminster modern systems, while the recent "upgrade" to Win7/2008 has made so many changes to the interface that it seems like I have to relearn it each time I use it.

Unlike Linux, I don't think this has been patched.
I once had a computer which did that, a Commodore 64. I am pretty sure most others at that time were that way too. The whole "store the O/S on a R/W hard drive" was an IBM PC/Microsoft idea, as were viruses.
A ROM based system with Ubuntu or Knoppix would be pretty sweet for surfing teh Interwebs.
I'm guessing that less than 2% of you know probably what the heck I'm talking about here.
Missed it by THAT much? Agent 86 once said that after he almost shot his dick off. I wonder if he ever screwed Agent 99? Man, I used to think she was hot. And the Cone of Silence? I saw a real one in action while on jury duty once. The judge lowered this stupid contraption when he was talking with the lawyers. It made this white noise which gave everyone headaches but I had no problem hearing their entire conversation from the other side of the room...
The parent is wrong. Nothing has replaced the A-10. The Pentagon tried to kill the Warthog earilier this year until everyone who actually uses them screamed bloody murder.
This fricken plane is airworthy with half a wing and an engine missing. Could the F-35 do that?
The Iraqis don't want us to send troops over there to deal with the ISIS business. They have plenty of troops of their own. What they have asked for is some air support. Immagine what a couple of A-10 squadrons would do there..
