Can you trust what Grok tells you?

No, not by default — not because Grok is uniquely dishonest, but because fluency is not a witness statement. Trust is earned per claim: a source you opened, a test you ran, a number you recomputed, a person you asked. Grok can help you do all of that faster. It cannot be the last signature.

Use it as a brilliant junior. Keep the parts that can hurt people, money, or reputation on a slower path.
