Another epic tale from Richard Powers. This one appears to be about friendships and class and the competitiveness of young people, the differing trajectories of lives. The kid from the poor Black neighborhood and the kid who grew up privileged but also with parents who kind of hated each other. It’s also about the way the world is mostly ocean and the complex ecosystem that exists there mostly unseen. There’s a woman who likes to go scuba diving who figures prominently as a bit of a third character. But it’s also about AI and there are about two sentences where you realize, you might realize, that the plot is different than you expected or thought it was. And I had all sorts of weird feelings about that. I don’t know what they call it when the book turns out to have a large part of it which seems true at the time but then is shown (maybe) not be true? This is one of those.
