In Cognitive Kin, Christophe Kolb and Jan Rosen map the threshold where AI becomes a colleague to reshape the meaning of work and create new sources of value. Drawing on firsthand experience at the frontier of agentic AI, the authors show how digital labor becomes viable, why org charts give way to networks of intent, and how leadership shifts to orchestration. They translate the machinery--memory, feedback loops, tool use--into plain language, then follow the shockwave into strategy, culture, and governance.
