The Glass Cage: Automation and Us by Nicholas Carr explores the hidden costs of increasing reliance on automation, arguing that while it makes life easier, it can dull human skills, narrow perspectives, and diminish our autonomy by offloading critical thinking to machines. The book examines the impact of automation across various fields, from aviation to medicine, and serves as a cautionary tale about the potential for technology to replace human judgment and expertise, advocating for a more human-centered approach to design.
