its interesting - but there is something fallacious here: "Probably the most important lesson to be learned from the past 60 years of software development is that global mutable state is bad. Really bad." This represents a misunderstanding about the badness of global variables and the goodness of encapsulation in my mind. Mutable global state is an unavoidable necessity to ship your app - every single pixel on your screen is a bit of global mutable state. I won't dive to far in here, but I cringe everytime I see these fancy pants words applied because its pretentious /and/ trivially measurably wrong (see everything on your monitor right now).
