I found this a frustrating book.
It's about artificial intelligence, whether or not we'll achieve it soon, and whether or not it will be good for mere human beings if we do. And while I suspect Bostrom doesn't think so, I found it, overall, depressing.
First, he wants us to understand that, despite repeated failed predictions of imminent true AI, and the fact that computers still mostly do a small subset of what human brains do, but much faster, and we don't even know how consciousness emerges from the biological brain, strong AI is coming, and maybe very soon. Moreover, as soon as we have human-level artificial intelligence, we will almost immediately be completely outstripped by artificial superintelligence. The only hope for us is to start right now working out how to teach the right set of human values to machines, and keep some degree of control of them. If we wait till it happens, it will be much too late.
