"The Shallows" is a book by Nicholas Carr that explores how the internet affects our ability to think and concentrate. Carr argues that constant online distractions can lead to shallow thinking, making it harder for people to engage in deep, meaningful thought. He examines the neurological changes that occur in our brains as we adapt to digital technology. The book discusses various studies and historical perspectives on reading and cognition, highlighting how different media influence our mental processes. Carr also reflects on the implications of these changes for society, suggesting that our reliance on the internet may diminish our capacity for critical thinking and creativity.
