If anything KSR is not giving himself as much credit as he deserves, as personal AIs show up in ways that are remarkably salient and similar to what we're currently seeing. And he talks about advances in genetics that parallel what we're figuring out with CRISPR at least to some degrees. The biggest "error" is the preoccupation with a Paul Ehrlich-style population boom, but by the same token it reveals that the book is a window into the time it was made.
If any ambitious and aspiring science novelists are reading this, I would love for someone to be the Kim Stanley Robinson of Venus and tell the story of colonization there, aspiring to the same bar of technical specificity that KSR had for Red Mars.
