We need the internet. No, seriously. In 2023, the digital realm isn’t so much a portal as it is the undercurrent of our lives: The web carries our culture, our communication, our bank accounts — and, yes, our global security.

But all of that traffic flows through a series of cables at the bottom of the ocean. And lately, we’ve been worrying a lot about it up on dry land: Asking what happens when something — or someone — cuts those cables. Should we really be so worried?

This is a story about volcanoes and sharks, entrepreneurs and politicians. It’s also about none of those things. Welcome back to Things That Go Boom.
