I sincerely believe that programming has gone through a couple of paradigms over the decades. For instance it used to be a good thing to never be scared of architecting a solution from the ground up (and the best often did) whereas nowadays our ecosystem of libraries and tools are so vast that it much more often is overkill, and the architect mentality often a handicap. (This is obviously just one person's opinion)

Sounds principles are sometimes tied to these paradigms. For instance in past years one could maybe say "never use a tool that you don't know well" whereas nowadays with all of the layers of technologies that you are forced to work with it may have changed to just knowing why you have to use a technology and knowing well the aspects that you are using it for.

Also, there are by now many generations of programmers, and we might not want to admit it but the people that grew up on assembly do tend to have different sensibilities than the people that grew up on scripting languages. With these generations often come ingrained mentalities that are tied to paradigms that are tied to principles which in fact are still subject to change.
