When people say "multitasking," I think they really mean "heavy context switching." It's important to re-frame the idea because actual multitasking is /extraordinarily/ difficult. It takes years or decades to master multitasking in even one, very specific arena (e.g. playing the drum set, or understanding two conversations simultaneously).

Heavy context switching, on the other had, is more readily doable by human beings, but still highly inefficient. It would be much better if people focused on prioritizing work more effectively, and then proceeded in a serial manner. Of course, prioritizing work is not easy, especially in complex systems, but the time freed up from constant context switching would help.
