Still in the middle of reading this. Really interesting how the modern Silicon Valley ethos goes all the way back to hippies experimenting with new tech as a means of counterculture. Honestly, you can track the Fediverse back to here. That's not always a good thing, though - the book goes over how this ethos was appropriated in the 90s.

Based on what I've read so far, you really need to read this with a critical eye. It's a tragic story, but the author doesn't seem to be aware of it. It's also overfocused on one guy, Stewart Brand, despite the movement being bigger than him. It's a good read, but be aware that it has its flaws.

Maybe I'll leave a full review when I finish it.
