This chapter introduces the concept of cognition technology, of which artificial intelligence (AI) is the most prominent example. The urgency of understanding AI not merely as information and communication technology, but as a technology of cognition is motivated by moral considerations concerning a distinctive form of vulnerability that we, as cognitive agents, acquire through exposure to technological systems, the success of which depends on us alienating from our cognitive skills, states, and processes and on us subsequently substituting them with computational means. We need to understand the disruptive potential of AI, as a cognition technology, for moral agency, for which deliberation, reasoning, and sense-making are fundamental constituents.
