We are history: we used to write letters, and today we type emails, chats, posts, and notes on our phones; we dictate messages and send voice messages. But when did this transformation of our relationship with language, as well as with machines, begin? How has Italian changed since the first text messages were sent to dialogue with so-called artificial intelligence? Alfabit is the story of the intersection between linguistic tradition and its computerized translation. In other words, the close link between the evolution of Italian and the succession of new technological media. New codes of communication have gradually reduced the distance between written and spoken language, favoring the emergence of widespread informality and increasingly fragmented texts. The result is a language dictated by the pace of simultaneous interaction: fast, ephemeral, immediate, and marked by spontaneity. The author reconstructs the different phases of this metamorphosis in real time. From the typed Italian of text messages and emails to the e-Italian of chats and social networks to the AI-Italian of ChatGPT and other Large Language Models. An extraordinarily topical story that, through language, helps us understand a little more about the world we live in.
