The author argues that the rapid pace of technological change has led to a loss of control over the information we consume, and that this has had a profound impact on our ability to think critically and make informed decisions about our lives. The book begins by examining the ways in which technology has influenced our perceptions of reality, from the invention of writing to the rise of social media. The author argues that each new technology has changed the way we think about the world, but also that these changes have not always been positive. For example, the invention of writing allowed us to record and transmit information more efficiently, but it also led to the development of bureaucracies and hierarchies that limit our freedom and creativity. Similarly, social media has given us new ways to connect with others, but it has also created echo chambers that reinforce our existing beliefs rather than challenging them. The author then turns to the concept of flash memory, which he defines as the ability to quickly and easily access and process large amounts of information. He argues that this technology has enabled us to store and retrieve vast amounts of data, but that it has also led to a loss of depth and nuance in our understanding of the world. In particular, he notes that the ease with which we can access information online has made it easier for us to ignore or dismiss complex issues, such as climate change and economic inequality.
