You've got that back to front.

It's the GUI users who are the Neanderthals, having to effectively point 
at things with sticks. Or have to physically move that rock themselves 
(ie. drag a file to a wastebasket).

More advanced uses have the power of language, with all its 
sophistications (ie. commands lines and scripting). And they don't need 
to move that rock, they can tell someone else to do it! But with far 
more control: all rocks of a certain size and colour, and at sunrise 
tomorrow.

Some things are just more easily described with a script or formula or 
algorithm which is then 'rendered' to produce the result. Not quite 
right? Change one parameter to re-render to instantly produce a new 
version, that would have taken minutes or hours to do manually.

You have to give someone some shopping to do. What's quicker, jotting 
down a list of milk, bread, eggs and so on, or invoking some GUI program 
where you have to first look for each category, then have to choose the 
exact subcategory, size, quantity...
