Tardiness is next to wickedness in a society relentless in its consumption of time as both a good and a service--as tweet and Instagram, film clip and sound bite, as sporting event, investment opportunity, Tinder hookup, and interest rate--its value measured not by its texture or its substance but by the speed of its delivery, a distinction apparent to Andy Warhol when he supposedly said that any painting that takes longer than five minutes to make is a bad painting.
