Richard Powers may just be the bravest big novelist out there. His new book is titled Playground, in which AI plays with the natural world. The question is whether and how the digital transformation might undo the power of death, as in the death of long ago people, the death of species today, even the death of a planet.

Richard Powers.

This is our third trip through a new book of his, aiming his imagination and hard science at the scariest maladies of modern life. First it was Orfeo, about atonal music, then The Overstory, which won the Pulitzer prize and a huge audience, about disappearing tree species. And now Playground, going deep into the breakdown of oceans—also into dementia with Lewy bodies, also fate and friendships, and damaged people who make foolproof thinking machines.
