Medical AI 'cures' cancer but infects patient with Banach-Tarski paradox in viral math meme

A viral math-flavored joke imagines a medical AI declaring a patient's cancer cured—only to announce, deadpan, that they now "have the Banach-Tarski paradox" because the system used the axiom of choice and nobody checked the implications, adding "Terence Tao warned us and we didn't listen." The punchline: may we dissect you and reassemble the parts into two complete patients to study the condition?

The meme works as a jab at AI systems whose outputs look correct while their unchecked reasoning imports absurd side effects—a lighthearted analogy for today's explainability gaps in deployed models.
