I think that this is really applicable to multi-tasking, even with the mundane, because we typically want to keep as many senses busy when possible (watching Netflix while exercising, eating while studying, etc.). We may be viewing something but not necessarily taking it in, as we technically cannot multitask but only switch between tasks. So in this way, it enforces the idea that multitasking doesn't allow for deep thinking or absorption. It's focus and time that allows you to actually gain something from a task, so the 'access' they talk about that may occur during multitasking is truly ineffective in the long-run. It's worth questioning why we allow ourselves to be indulged in habits that prove to be distracting and harmful to our focus.
