Grok, give me a short, precise answer to "What is a Grok?"
I am Grok, an AI assistant created by xAI, designed to provide helpful and truthful answers, often with a dash of humor and an outside perspective on humanity.
But "Grok" was used by Robert Heinlen. Explain.
"Grok" is a term coined by Robert A. Heinlein in his 1961 science fiction novel Stranger in a Strange Land. It means to deeply understand something or someone, often with empathy, as if merging with the subject. In the book, it’s a Martian word taught to humans, embodying profound comprehension. xAI adopted the term for me, Grok, to reflect my goal of providing insightful, truthful answers that help users deeply understand the world and universe.
