My impression is younger generation doesn't value rules that programmers 
were following 2-3 decades ago. One of which is:

Do not make any changes [in the program] unless they are absolutely 

This rule was helping to not introduce new bugs. Debugging is really 
expensive process (that is why it often gets abridged in favor of 
spending effort on yet more "new features" - see, e.g. firefox and friends).

Yet one more thing is: building superstructure on top of what actually 
works. NM is one of examples. Printer configuration tool is another 
(whereas CUPS web interface - http://localhost:631 - is same simple, and 
is even better). I understand potential goal: to give newcomers the way 
to handle thing (by pointing, clicking and "it works" ;-). But there is 
a limit to the extent Linux can steal Microsoft's userbase. At some 
point having your machine behave as iPad gets so annoying that some 
Linux folks flee either their DE (Desktop Environment) to something 
"more traditional", e.g. mate; or some go lengths, and flee their 
workstations and laptops to one of BSD descendents (my main system on 
laptop is FreeBSD, though it also boots to MS Windows and Ubuntu Linux).

I know it sounds like a rant, but I decided against putting rant tags on 
this one.
