In Book - Deep Work.. 3 Rules for Focused Success in a Distracted World, Cal Newport raises a question: If connectivity is so detrimental to our output, learning, and general productivity, why do we spend so much time doing it?
The answer he supplies: It is easier than real work and feels productive. People gravitate towards the path of least resistance that still feels somewhat productive.
Furthermore, CEOs engage in that kind of behavior, so other people think that there lies the secret to productivity/output, see The only job where deep work can be ignored is as an executive at a big company
That is also why students like to visit lectures even though they do not take away a lot from them, as it feels productive and like learning (make a separate note for this concept in the future?)
