How long will humans have left?

No one knows exactly how long humans will last, with predictions ranging from a few centuries due to self-inflicted risks like climate change, nuclear war, and AI, to millions or even billions of years if we spread to space and overcome threats, with some statistical models suggesting extinction within 8 million years or even as soon as 760 years, but optimistic views point to Earth's habitability for another billion years if we manage our challenges.
