It's 2040. We are no longer afraid of Artificial Intelligence because we have found that it helps us to diagnose diseases and identify cures, to pollute less and to find materials and processes that are really able to cut emissions, indeed that in their production they can sequester CO2. We are no longer just talking theoretically about green and sustainability and circular economy: we are really making a difference and our cities are finally clean and welcoming, they are cities for people, where green is not just maquillage but is wanted, lived and cared for with awareness and care and water (waterways) is a friendly and positive component. People, even the common and inexperienced ones, have learned to use Social Media with respect, they know English and no one dares to use aggressive tones anymore. Have we grown up? Perhaps.
