Peter Frase sets out not to make accurate predictions about the future, but in very broad strokes to describe four possible futures, based on two axes: scarcity/abundance, and authoritarianism/freedom. He gives us visions of those futures and not detailed descriptions, because as he himself writes, such a thing is impossible.

In my opinion, such an undertaking is useful, for people to be able to set courses and be clearer about what kind of future they're fighting for.

I imagine that reading this book expecting something more precise would lead one into disappointment. I was not disappointed.
