This collection of essays develops a set of ideas around the prospect of AGI and how we as humans should handle it. The essays vary in topic and depth. A lot of it focuses on responding to Yudkowskyian style thoughts around AGI, and so it has some of that flavor of LessWrong content, though in a more elegant and humanisticly educated style.
But a few of the essays are more tangential to AGI, and these, I think, are the better works in the collection by far. In particular, the essay On Attunement is a beautifully written meditation that reaches for, and I think finds, something quite deep about human experience and the universe. As with many of the best writings, On Attunement is itself an instantiation of its subject, and there is no higher praise I can offer.
On Attunement is a masterwork, and its well worth reading the whole collection just to have the full context for that one essay.
4/5 because On Attunement is 5/5 and much of the rest is nearer a 3 (which on my scale is still pretty good)
