As we can read from this article and Facebook’s internal management debates, Web 2.0 (of which the GAFA companies are the archetypes) is built on a data land grab. It’s rather similar to the actual land grab that the European powers battled over for the New World, then with the colonization of Africa and Asia.
Data is now a valuable resource that has been priced up there with land and capital. Naturally, the tech oligopolies and their startup wannabes all want to grab as much as possible. And who are they grabbing it from? The network users of course.
Web 3.0 is all about democratizing the value and monetization of personal networked data. It’s about decentralized ownership and control, much like the desire to own and control the fruits of one’s labor that ended slavery. Web 3.0 is the future, because Web 2.0 is unsustainable.
