"But smart ones remember that it's motto of a system which is dead and buried"
*Not* dead and buried. Those of you who wish to write massive bloatware and spend the rest of your lives debugging, have fun.
The real smart ones will settle for "worse is better," and "Doing one thing well [enough]." And those who do will not be stuck in a quagmire of runtime engines and debuggers. They are the ones who will actually get their tasks done and their legacy will be a handful of scripts that are still used years after their authors' deaths.
