There are enough people who earn a living without stepping into an office. A wartime correspondent can get a Pulitzer without being in office for months. A job that can be done with no interdependencies can be done from anywhere. The gig economy is proof of that.However, deeper bonds are formed between people who cross each other several times a day. In the late 1940s, psychologists Leon Festinger and Stanley Schachter, and sociologist Kurt Back found that physical space was the key to friendship formation.In a hyperconnected world, the notion of friendship is acquiring new shades. Online friendships are being formed on social media over shared interests. Whether these friends could work together on a day-to-day basis on tasks remains to be studied.
