This of course is a question that could have a number of answers. A very broad question indeed.
In truth, do we need anything?
As someone living in the Western world, we have shelter, food, relationships, employment...
Everything beyond that is really a degree of want, with a great virtue being the want for nothing
We do need:
-Truth
-Honest and lasting relationships
-Good leadership
-Objective Moral standard
So in short, NO... I don't think we need Kontakt 6 at all. But do we want it?...
Now there is a far more accurate query!
