What is this book about?

"Anticipations" is a collection of essays where Wells speculates on the long-term effects of scientific and mechanical progress. He wasn't just predicting specific gadgets (like flying machines or radio communication, which were then largely unknown to the general public), but rather examining the profound shifts in human society, economy, family structures, leisure, and even the nature of truth and belief that such progress would inevitably bring. He uses his knowledge of contemporary science, economics, and social trends to extrapolate towards a future that would later seem remarkably accurate.
