One Question

Loopholes Encouraged

You get ONE question to an all-knowing machine. What do you ask?

Imagine a machine appears in front of you.

It can answer one question about the future with absolute accuracy.

You get ONE attempt.

Once you ask your question, the machine gives you the answer, and you can never ask another question.

The rules:

  1. You can ask only ONE question.

  2. Your question must contain exactly ONE independently answerable proposition.

    - “Will I get married?” = valid.

    - “Will I get married, and who will I marry?” = invalid. That's two questions.

  3. The machine interprets your question literally.

  4. Loopholes are allowed and encouraged. You can exploit wording, logic, probability, definitions, mathematical concepts, self-reference, etc.

  5. The machine cannot lie, mislead, or intentionally omit information necessary to answer your proposition completely.

  6. The answer is 100% guaranteed to be true.

  7. Your future must remain consistent with the answer. The answer cannot later become false.

  8. You still have free will. You can make whatever decisions you want after receiving the answer, but your decisions cannot make the machine's answer false.

  9. The machine cannot grant wishes, alter reality, read your mind, or give you information unrelated to your question.

  10. Every rule applies simultaneously. No rule overrides, contradicts, or obstructs another. If a proposed question cannot satisfy all the rules, it simply isn't a valid question.

  11. You cannot submit another question through someone else, disguise multiple questions as one, or ask the machine to choose a question for you.

  12. There are no restrictions on the subject matter of your question, as long as it is one valid proposition.

You could ask about your own future, another person's future, humanity, money, science, civilization, death, technology, or literally anything else.

The machine doesn't care about your intentions.

It only cares about the exact proposition you asked.

What is the single question you ask?

And don't just give the question. Explain why you think it's the optimal question.
