I'm conflicted... In some ways I'd say this was 4 stars, but overall I'd give it a 3. I really enjoyed the writing style and a lot of the ideas presented (though I'm biased as philosophy in futurism is possibly my favourite subject), but there were definitely pacing issues in this book. I found myself losing and regaining interest every few minutes (the literary equivalent of doing the head nods before you're about to pass out). That said, I'd still likely read another DeLillo novel in the future.
