I'm not sure no. 1 contradicts the post's main point, but it certainly complicates it. There are definitely many people who are rapidly flipping between task to task (my sense is that producers, production assistants, and personal assistants fall into this category). There are also jobs like focus pullers and various techs who are working in a chaotic, changing environment, but are focused on one (difficult) task. It seems like a large film has people across varying both in how focused they are (few versus many tasks) and how responsive they have to be.
