This month, the 8 billionth human was born. But that number can elide a sobering fact: Population trends in many parts of the world have been dipping, even as growth is still robust in much of the Global South. It’s a phenomenon that will, as much as any other trend, shape the future.
The world to come
Earth’s population passed 8 billion this month — now what? Plus: the rise of an anti-vaccine America, the looming dangers of superintelligent AI, the shifting landscape of higher ed, and more.


That future is the loose theme of this edition of The Highlight, created by the Future Perfect team at Vox. Future Perfect is the section of Vox that looks at stories that are sadly neglected but truly important. Whether that’s surfacing the innovations reshaping society, calling attention to policies that are quietly monumental, or interrogating ideas that could reshape moral and ethical norms, Future Perfect is a guide to the future that will be — and could be.
That approach is what animates this edition of The Highlight. We hope you enjoy it.
