Worrying trend of modern day knowledge workers

In the book Deep Work , Cal Newport mentions that in the absence of a need for deep work , knowledge workers are very busy checking emails frequently , attending/setting up meeting requests and engaged in tasks he terms as “busyness as a proxy for productivity“.

This is indeed alarming as well as illuminating since in the absence of a proper metric for productivity , knowledge workers are busy engaging in activities which were the central theme of the Industrial Age.

Like a metric e.g. h-index(used for research) , the modern day knowledge worker should be encouraged to do deep work by means of such pointed metrics to help unleash creativity to take the human race progress even further in the modern Conceptual age driven by knowledge workers.
