A essere onesti, dobbiamo ammettere che l’aspetto centrale di questi incessanti aggiornamenti e continuo divenire del mondo tecnologico è quello di creare vuoti nel nostro cuore: non molto tempo fa, abbiamo tutti deciso che non potevamo vivere un giorno di più senza smartphone; qualche anno prima, questa stessa affermazione ci avrebbe sbalordito. Ora ci arrabbiamo se la Rete è lenta, ma in passato, quando eravamo innocenti, non avevamo nemmeno il concetto di Rete. Continuiamo a inventare cose nuove che generano nuovi desideri, nuove lacune che dobbiamo colmare.

In a letter Orville Wright wrote to his inventor friend Henry Ford, Wright recounts a story he heard from a missionary stationed in China. Wright told Ford the story for the same reason I tell it here: as a cautionary tale about speculative risks. The missionary wanted to improve the laborious way the Chinese peasants in his province harvested grain. The local farmers clipped the stalks with some kind of small hand shear. So the missionary had a scythe shipped in from America and demonstrated its superior productivity to an enthralled crowd. “The next morning, however, a delegation came to see the missionary. The scythe must be destroyed at once. What, they said, if it should fall into the hands of thieves; a whole field could be cut and carried away in a single night.” And so the scythe was banished, progress stopped, because nonusers could imagine a possible—but wholly improbable—way it could significantly harm their society. (Much of the hugely disruptive theater around “national security” today is based on similarly improbable scenarios of worst-case dangers.) In its efforts to be “safe rather than sorry,” precaution becomes myopic. It tends to maximize only one value: safety. Safety trumps innovation.

The stability of species. Take the number of species that we now consider extinct. For a long time scientists took the number of such species as that implied from an analysis of the extant fossils.
