My point is not to denigrate any popular process or advanced technological tools. And I don't embrace big design up front for everything, especially when it makes it even more easier (and more expensive) to paint yourself into a corner. I wanted to draw attention to a simple fact: sometimes the medium of production is not necessarily the best medium for thinking about that production and being immersed in that medium can prevent you from realizing this, thanks to the human psychology that took hundreds of thousands of years.
