Since the beginning of the 21st century, global warming, terrorism, the pandemic and now the war in Ukraine have created a widespread feeling that the world is an increasingly dangerous place. In response to this situation, it is understandable that many people are inclined to retreat to the safety of their home - the last refuge and safeguard against the savagery of the outside world. But the home is not just a shelter: it is a space that supplants and replaces the world, a wired cocoon that gradually renders any journey to the outside world superfluous.

Compulsory confinement, the nightmare of the pandemic years, seems to have been replaced by voluntary self-confinement.
