At the end of the adventure of this book, we would like to conclude by coming back to the implications of posthumanism for the grand challenges of our time. Climate change, geopolitical crisis (with war), nuclear threats, the crumbing of sense at work, surveillance capitalism, and rising inequalities all of these dangers converge in one way or another to an old will of control. They originate in too-humanistic paths in the world. From there, posthumanism can lead to two different approaches: a processual posthumanism and a critical posthumanism. These two complementary approaches are detailed and implications are drawn for management and organization studies.
