> Where is the historical analysis? Is it more apocalyptic now than during the cold war when kids hid under their desks?

the Cold War apocalypse was solely military in nature which had few implications economically, whether you get nuked or not doesn't change an investors strategy, you just assume the world doesn't end and carry on. The cold war calculus was if anything maybe the most rationally (albeit scary) period of human history, but exceptionally stable.

There is a difference between billionaires being afraid of the communists, which was of course self-serving, hysteric and at times bigoted, but the communists were at least real and had killed some few ten million people. That's a very different form of apocalyptic thinking than billionaires giving lectures on the actual Anti-Christ in the Vatican.

Economic manias happen in periods of social transformation and hot war, not cold ones. And on that front we do look a lot more like we are in the 1920s, or some bizarre 19th century evangelical revivalism period rather than the 1960s.

I'm not sure about that, I think it would make me favor investments in science and technology, or if college age I would likely choose engineering over say art. The "Sputnik Shock" did have a cultural effect not to mention more direct methods like the National Defense Education Act.
