Several entities with artificial intelligence (like self-aware computers and androids) suffered from severe internal systems failures after they had been made aware of paradoxes or other dilemmas. Being guided by logic, these artificial intelligences were unable to cope with logically insoluble problems. Captain James T. Kirk was quite adept at inducing self-destruction in artificial intelligences, or "talking computers to death." He achieved the feat at least four times.
