Well that is what the book is about, it is a speculative look at what hypothetical superintelligences might look like, it is explicitly not about the real world at all. Remember that the author is a philosopher, not an engineer, philosophy is all about hypotheticals.
Philosophy is not all about hypotheticals. Philosophy of technology especially is mostly about technologies that already exist and their impact on society. Not speculation.
Some philosophy (of technology, among others) relates to that, not all. It is not necessarily all about concrete impacts either, it depends on the author and their interests.
