Nope none of them.

detail more than capable of getting some top level engineers interested and then making it real.
ROBERT A. HEINLEIN: THE TOR.COM BLOG SYMPOSIUM
Robert A. Heinlein’s technological prophecies
Robert A. Heinlein’s fiction excelled at predicting the effects of technology, how particular tools would change society and the lives of people who used them daily. He usually didn’t predict the details, but his predictions of what technologies would mean were often uncanny.
The most dramatic example of this kind of prediction is “Solution Unsatisfactory,” a story which Heinlein wrote in 1940, which predicted the Cold War before the U.S. was even in World War II, and before the Manhattan Project. In the story, the U.S. develops a nuclear weapon and, for a brief time, is the only nuclear power in the whole world. America knows that its enemies will get the weapon soon. That much actually happened in real life, five years later.
But the story of “Solution Unsatisfactory” takes a different turn than real-life events turned out. In “Solution Unsatisfactory,” the head of the nuclear weapons project overthrows the government of the U.S. and sets up a global, international dictatorship with monopoly control of the nuclear weapon. And that’s the unsatisfactory solution of the story—the narrator of the story, the head of the nuclear weapons project, and presumably Heinlein himself all hate this option, but see the only other alternative, a global nuclear war, to be worse.
Was Heinlein’s unsatisfactory solution a nightmare scenario which we blessedly avoided? Maybe. But instead, we got 40 years of Cold War, the U.S.S.R. dominating half the developed world, and the U.S. propping up nasty dictatorships in the other half. And just because the Cold War is over, the threat hasn’t gone away; nuclear weapons are still common, as are governments and organizations willing to use them.
Heinlein was writing about these issues before nuclear weapons had been invented. He got the effects of the technology right, but he got the technology itself wrong. The weapon he predicted wasn’t a bomb, it was radioactive dust. ( yep our real worse case nightmare for the future of the planet is not theexplosive nuvlear blast it is the convention blast but of a "Dirty Bomb".
Also in 1940, Heinlein published “The Roads Must Roll,” a story in which enormous conveyer belts replace railroads and highways as the dominant means of transportation in the U.S. Long, thin cities grow up along the sides of these roads, just as suburbs sprouted along superhighways a decade later.( I have been to LAX and they had the so called horizontal escalators. They were four tracks wide and each track increased speed from casual walk and then slow jog and then good run and then Olympic Sprint speed.ou started on the slow track and then stepped til you got on the fast one if ou had a ways to go to your terminal gate to get on board.) In the Heinlein story, restaurants sit on the roadway itself, and you eat while in motion. We don’t have that in real life, but we do have what seems to be the same exact Denny’s replicated every three miles on the highways of southern California.
“The Roads Must Roll” is a story about the technicians essential to operating the roads, the dominant transportation system in America, and how these technicians have the power to credibly threaten to shut down the American economy by going on strike. The story played out in real life in 1981, with the threatened strike of the Professional Air Traffic Controllers Organization (PATCO). Again, real life played out differently than it did in the Heinlein story; in real life, President Reagan fired the air traffic controllers.
The leader of the road technicians’ strike was the villain of the Heinlein story, I’m not drawing the same conclusion about the PATCO strike, just noting the parallel of a relatively small number of technicians in a key transportation industry able to threaten economic chaos by going on strike.
Heinlein also invented the internet. In his 1938 first novel, For Us The Living, unpublished during his lifetime, Heinlein predicts a nationwideinformation network, from which the hero is able to instantly access a newspaper article from the previous century, from the comfort of a friend’s home. Today, theNew York Times Archive is online, witharticles datingback to 1851.
