Today, in many advanced information societies, asking whether one is online or offline has become meaningless. Imagine being asked whether you are online by someone who is talking to you through your smart phone, which is linked up to your car sound system through Bluetooth, while you are driving following the instructions of a GPS, which is also downloading information about traffic in real-time. The truth is that we are neither online nor offline but onlife, that is, we increasingly live in that special space that is both analog and digital, both online and offline. An analogy may help. Imagine someone asking whether the water is sweet or salty in the estuary where the river meets the sea. That someone has not understood the special nature of the place. Our information society is that place. And our technologies are perfectly evolved to take advantage of it, like mangroves growing in brackish water. In the mangrove society, all relevant (and sometimes the only) data available are machine-readable, and decisions as well as actions may be taken automatically, through sensors, actuators, and applications that can execute commands and output the corresponding procedures, from alerting or scanning a patient, to buying or selling some bonds. The consequences of such radical transformation are many, but one is particularly significant and rich in consequences: what is the human project we should pursue in designing the mangrove society? This is the question I shall discuss in the talk, in view of exploring a possible answer.
