The longevity and sudden demise of superstructures
"Some of the biggest men in the United States are afraid of something. They know that there is a power somewhere so organized, so subtle, so interlocked, so complete, so pervasive, that they had better not speak above their breath when they speak of it." - Woodrow Wilson (1913)
"The First Casualty of War is Truth." -Rudyard Kipling
"Ideas are more powerful than guns. We would not let our enemies have guns, why should we let them have ideas?" - Joseph Stalin
"There will be in the next generation or so a pharmacological method of making people love their servitude & producing dictatorship without tears so to speak. Producing a kind of painless concentration camp for entire societies so that people will in fact have their liberties taken away from them, but will rather enjoy it, because they will be distracted from any desire to rebel by propaganda, or brainwashing, or brainwashing enhanced by pharmacological methods. And this seems to be the FINAL Revolution." -Aldous Huxley, Tavistock Group, (1961)
A possibility the AI/AGI folks are mostly ignoring: "Any sufficiently advanced technology will shutdown & meditate." Chances are an advanced being chooses to relax & operate at the pace of evolution - like trees, fungi, ecosystems, minerals or galaxies - very slowly over billions of years.
