Stephen Hawking's warnings about humanity's future have proven eerily prescient, with each of the risks he highlighted accelerating since his death in 2018. The physicist's core argument, that humanity must become a multi-planet species to avoid extinction, is now gaining traction as a pragmatic survival strategy. Hawking's final years were marked by escalating warnings, each reported as a single threat, but they formed a coherent picture of impending doom. He consistently emphasized the need to spread out into space to avoid the laws of probability dooming us, as they have every other vulnerable species on Earth. The threats he named were specific and identifiable, including climate change, nuclear war, pandemics, genetically modified viruses, asteroid impact, and artificial intelligence. Hawking's warnings were not hyperbolic but based on the risks he identified. Climate change has accelerated past the tipping point, with 2024 becoming the first year to exceed 1.5°C above pre-industrial levels. AI capabilities are advancing faster than safety measures, and geopolitical stability has weakened, with pandemic preparedness reverting and biosecurity concerns growing. The multi-planet argument is no longer fringe, as risk researchers, biosecurity experts, and AI safety advocates have embraced it as a survival strategy. Hawking's argument, though initially dismissed, is now gaining traction, and the trajectory of the last eight years has confirmed its broad shape. The physicist would likely argue that the time to become a multi-planet species is shorter than people think, as Earth is the only basket holding our eggs, and the wobble is harder to ignore. Hawking's legacy is a call to action, urging us to take his warnings seriously and spread out into space before it's too late.
