He has slowly been going mad over the last 20 years. Unfortunately in his case it means mean mad; he’s joined the Orson Scott Card Literary Assholes Circle. The first hint of this was Rising Sun, which was a piece of racist shit pandering to the Yellow Peril mood of the 1990s. Remember? When Japan was going to take us over? It was made into an even worse movie. Thanks for topping us up, Mike, we didn’t have nearly enough race hate.
And then we had Airframe, which as far as I could tell was a screed against the whole idea of consumer safety or product liability lawsuits.
Finally he’s really gone and done it, with an antiscientific novel that attacks climate science, complete with a recondite appendix full of graphs and charts showing how all those pesky scienticians are wrong. He comes perilously close to ringing the Godwin Gong by comparing the “safety culture” to totalitarianism. More details here.
Maybe for his next opus he’ll novelize The Bell Curve or collaborate with Dave Sim in an attack on the Other Half!
