What Do They Know That You Don't?

Mark Zuckerberg is building a 5,000 square foot underground shelter in Hawaii with its own independent power, food, and water. Sam Altman stockpiles radiation medication, antibiotics, and gas masks. Peter Thiel has properties in New Zealand and openly discusses civilizational collapse. Elon Musk is building a rocket to Mars.

 These are not paranoid fringe figures. These are the most successful, well-informed, and analytically rigorous people on earth. And they are all independently reaching the same conclusion.

 What do they know that you don't? What are the wealthiest and most connected people in the world actually doing in the preparedness space, what categories of risk they're preparing for, and what the convergence of their behavior tells regular families about what's coming.
