Walking down the street on my lunch break, I sometimes pass a delivery man wheeling a large handcart of Japanese food. The cart bears a striking message: ‘Creating a world where everyone believes in their own authenticity.’ It raises some immediate questions: for instance, what does it mean to believe in your own authenticity? How would you go about creating a world where everyone does? And what’s it got to do with Japanese food?

It’s unfair to single out the delivery service.
