You can all supply your own favorite, most nauseating examples of the commodification of love. Mine include the wedding industry, TV ads that feature cute young children or the giving of automobiles as Christmas presents, and the particularly grotesque equation of diamond jewelry with everlasting devotion. The message, in each case, is that if you love somebody you should buy stuff.

A related phenomenon is the transformation, courtesy of Facebook, of the verb “to like” from a state of mind to an action that you perform with your computer mouse, from a feeling to an assertion of consumer choice. And liking, in general, is commercial culture’s substitute for loving. The striking thing about all consumer products — and none more so than electronic devices and applications — is that they’re designed to be immensely likable. This is, in fact, the definition of a consumer product, in contrast to the product that is simply itself and whose makers aren’t fixated on your liking it. (I’m thinking here of jet engines, laboratory equipment, serious art and literature.)
