Reading your excellent post makes me sad because you are absolutely right. The need to multitask in academic life and carry ever larger burdens of work to the point where sleep becomes a luxury also means that our work will tend to be more shallow. I have two kinds of work that cannot be shallow, and to my dismay, I have little time for either.
One kind of work is being present for students. Just making myself available. Instead, I will spend my office hours on email, writing quiz questions, or producing documents, and hope that nobody will stop by because I’m too busy! This is the opposite of what needs to happen.
The other kind of work that requires deep presence is grading. No multitasking here! It takes time to do a thoughtful, thorough, and consistent job. Without the luxury of large chunks of time to focus on grading, I often think that I would get more “work” done if I just stayed home. (Except I would not be present for students!) Sigh. Rather than just take my attention away from work 1 and work 2, electronic distractions need to be harnessed to somehow do “shallow” work for me so I’ll have time for deep work.
