And speaking of technology, today’s Luddites have a short memory. Parents who lament the iPods and mobile phones soldered onto the ears of teenagers forget that their own parents made the same complaint about them and their bedroom telephones and transistor radios. The abbreviated prose in tweets and instant messages is no more likely to corrupt the language or shorten attention spans than the telegrams, radio ads, and advertising catchphrases of yesteryear. Email can seem like a curse, but who would go back to stamps, phone booths, carbon paper, and piles of phone messages? And now that dinner companions can fact-check any assertion on an iPhone, we are coming to realise how many of our everyday beliefs are false—a valuable lesson in the fallibility of memory.
