Os Meios de Comunicação como Extensões do Homem (Board book)

His idea that media are extensions of ourselves feels so relevant today, but I wonder what inspired him to frame it that way and how he visualized these extensions shaping society.

Some of his insights about television, the internet, and global village seem prophetic. I'm curious which predictions resonated most with others and which felt more speculative.

The ideas are fascinating but can be dense. Do readers feel this book is a good entry point, or would it be better to start with more modern summaries or commentaries?
