Final answer:
Langdon Winner uses the concept of technological somnambulism to describe how society uses technology reflexively, without conscious consideration of its potential impact, akin to sleepwalking behaviors.
Step-by-step explanation:
Technological somnambulism is a concept defined by Langdon Winner to describe a societal condition where people reflexively use or engage with technology without thorough consciousness of its effects on them and the world around them. This term relates to the idea of sleepwalking - a parasomnia where an individual performs complex actions while asleep, similar to how society interacts with its technological constructs. He suggests that as a society, we are in a state of somnambulism regarding our technologies, using them and integrating them into our lives without adequate reflection or understanding of the broader implications.
