Consider this: When you hear the term multi-tasking, how often is it spoken of glowingly, as an ideal goal to be sought with near-religious fervor, vs. being spoken of as the inherent compromise it actually is? Personally, I've never seen it referred to negatively, as something that was hindering the achievement of any desirable goal. And frankly, that fact makes me think that some amazingly effective cultural brainwashing has occurred. Everyone is brought to believe that "multi-tasking" means something akin to "two for the price of one" rather than being what it really is - 1.5 for the price of two, 2 for the price of 4, or 3 for the price of 9, etc. "We're going to force you to do so many things at once that you won't have the necessary attention or energy left to make effective plans, understand what you're doing, or make any sensible moral judgments about it."
It's the new form of making workers too tired to attend labor union meetings: Make them too distracted and intellectually occupied to form coherent subversive thoughts and effectively implement them into action.
