I can't speak for moxious, but I agreed with their post because in my understanding of business and engineering and from being around people of either backgrounds, engineering seems to firstly prize hard, analytical skills and only later on considers creative solutions, while business gets around to analyzing things after considering the things within a/the bigger picture.
In terms of seeing the forest vs. the trees: My thought is that engineering might be so concerned with seeing and analyzing the trees that they do not get around to considering the forest as a whole and recognizing where no tree presently (but could eventually) resides within that forest. (I think that "recognizing where no tree presently resides" is what a dreamer type might do.)
A big issue that I see with framing business people in this light is that few of them do seem to think entrepreneurially, but that may explain why you haven't run into more dreamer types.
