Modern English has given us two terms we need to explain this phenomenon: "geeking out" and "vegging out." To geek out on something means to immerse yourself in its details to an extent that is distinctly abnormal - and to have a good time doing it. To veg out, by contrast, means to enter a passive state and allow sounds and images to wash over you without troubling yourself too much about what it all means.Stephenson says the original Star Wars is a mixture of veg and geek scenes, while the new movies are almost all veg out material. The passive vegging out he describes is exactly how I think of the prequels (except that Episode III seems to have a couple of non-veg out scenes, which is one of the reasons I think it fares better than the other prequels). He also makes a nice comparison to the business world, but then takes a sudden sort of indirect dive towards outsourcing and pessimism at the end of the article, making a vague reference to going "the way of the old Republic."
I'm not sure I agree with those last few paragraphs. I see the point, but it's presented as a given. Many have noted Stephenson could use a good editor for his recent novels, and it looks to me like Stephenson was either intentionally trying to keep it short (it's only two pages - not what you'd expect from someone who routinely writes 900 page books, including three that are essentially a single 2700 page novel) or his article was edited down to fit somewhere. In either case, I'm sure he could have expounded upon those last paragraphs to the tune of a few thousand words, but that's what I like about the guy. Not that the article is bad, but I prefer Stephenson's longwinded style. Ironically, Stephenson has left the details out of his article; it reads more like a power-point presentation that summarizes the bullet points of his argument than the sort of in-depth analysis I'm used to from Stephenson. As such, I'm sure there are a lot of people who would take issue with some of his premises. Perhaps it's an intentional irony, or (more likely) I'm reading too much into it.
