Seth Goldstein comments:
Theres so many atomic units vying for attention, you need to be much more forceful about deciding what you are going to pay attention to. It has gotten to a point where you actually have to schedule your attention: Im going to pay attention to this person or this company at this time. In a world of TIVO-enabled time shifting, the time requirements go away because its fungible, because you can record it and watch it later, but you still have to slot it in somewhere. Theres a calculation you need to do. Even though the episode of 24 from two weeks ago automatically got stored, you still have to pay attention to it to receive the benefit of the information.
