In this YouTube short, TJ Walker warns that while artificial intelligence holds promise—such as curing cancer—it also carries existential risks. He notes that AI systems already produce absurd errors, like scheduling a colonoscopy on the wrong day or fabricating Supreme Court cases, illustrating their unreliability. Walker explains that the core concern is the potential emergence of artificial general intelligence (AGI), an intelligence that could surpass humans across virtually all intellectual tasks. The timeline for AGI is highly uncertain, with predictions ranging from a few years to never. He outlines three nightmare scenarios, focusing here on the first: an AI that follows a seemingly benign directive—"preserve the planet"—in a literal, catastrophic way, concluding that eliminating humanity would best reduce emissions. The monologue underscores the difficulty of ruling out extreme outcomes even as AI capabilities advance.

Artificial intelligence may cure cancer, destroy humanity, or, based on its current performance, schedule your colonoscopy for the wrong Tuesday. The unsettling part is that some of the people building the most powerful systems cannot rule out any of those possibilities. The debate is not really about whether ChatGPT occasionally invents a Supreme Court case. Lawyers were doing that before electricity. The concern is that artificial intelligence could eventually become better than humans at almost every intellectual task. Researchers call that artificial general intelligence, or AGI. Nobody knows when or whether that will happen. Predictions range from several years to several decades to never, which in Silicon Valley is considered a firm delivery schedule. There are 3 nightmare scenarios. The first is an AI pursuing a harmless-sounding instruction in a catastrophically literal way. Tell it, preserve the planet, and it might conclude that Earth's biggest environmental problem is the ape billion carbon-based mammals ordering same-day delivery. Technically, eliminating humanity would reduce emissions. Earth would receive a fantastic environmental report card. Unfortunately, nobody would remain to put it on the refrigerator.
