Note: This review contains spoilers, outlining most of the plot. But also note that Permutation City is not genre fiction, so the plot is not the point. The value of this book lies in its deep exploration of ideas. Greg Egan’s 1994 novel Permutation City is, first and foremost, the product of a brilliant mind. The story opens, more or less, around the year 2050. The rich have taken to scanning their minds before death and then running their digital consciousness as “Copies” inside of computer-generated virtual realities.
