Apparently Authority doesn't employ a single nerd. It's like predicting the results of horse races and having the odds drop as each successive race comes out as predicted. The revolution proceeds as it does precisely because it has a computer on its side. Politically Heinlein displays a striking lack of imagination. India is still starving poor.
Japan is invisible.
Kentucky is still virulently racist. The earthside section of the book is amusing but analysis-free. A guy on the Net accused Heinlein of racism and fake multiculturalism. The first charge is absurd. As for unreal multiculturalism, Heinlein is guilty as charged.
