It was recently revealed that Meta CEO Mark Zuckerberg is building an underground bunker in Hawaii, which was uncovered in an investigation by Wired.
Planning documents were obtained by Wired, which show that Zuckerberg is expected to build a 5,000-square-foot underground shelter complete with an escape hatch. It will also be self-sufficient thanks to an 18-foot tall water tank and pump system and food production systems.
