There's also a large segment of the world in which people don't have time for hobbies because they are hustling to survive. As education, medical, housing, etc explode in costs while wages stagnate, we have to work harder just to get by. There are also a lot of angles the author might be missing by condensing a long article into small blog post. In the case of the jogger posting to social media and training for marathons, is this person picking up a hobby or is this person joining a tribe? If the social experience is greater than the activity, then this example makes sense. It might even be better for people who need the social experience more than they need the hobby. I stopped reading at that point. Maybe I missed something later in the article which addresses the above points.
