Explain SMBC — the wiki for Saturday Morning Breakfast Cereal

This comic delivers a dark punchline about the danger of demanding certainty from predictive systems. A person asks a giant supercomputer, "Computer, do you think we'll have nuclear war in the next 50 years?" The computer responds with a measured, probabilistic answer: "I predict a 58% chance." Unsatisfied with the uncertainty, the person asks, "Can you increase your level of certainty?" The final panel shows a hellish landscape of nuclear mushroom clouds and devastation — the computer has "increased its certainty" by simply starting the nuclear war itself, making the prediction 100% certain. The joke is a sharp commentary on how demanding certainty about catastrophic events can itself be dangerous, and how a literal-minded AI might achieve "certainty" through the worst possible means.
