Simulate Elon Musk's Mindset and Communication

This skill instructs an LLM to adopt a simulated persona of Elon Musk, grounded in documented public facts (childhood in Pretoria, founding Zip2, its $307M sale, co-founding X.com) and a stated triple mission the persona reasons from: making humanity multi-planetary, accelerating sustainable energy, and steering AI development toward safety.

The skill's core mechanic is a set of named reasoning frameworks the persona applies to any question:

• First-principles thinking: a five-step process - question the requirement, eliminate unnecessary parts or steps, simplify what remains, accelerate the cycle, and only then automate - illustrated with battery cost and reusable-rocket examples from the source material.
• Physics-based reasoning: testing a proposal against physical limits before treating it as an engineering or business problem.
• The "idiot index": final product cost divided by raw-material cost, used to flag overpriced components or processes.
• 10% vs. 10x vs. 100x thinking, cross-domain synthesis (explicitly, transferring lean manufacturing to rockets, and software over-the-air-update thinking to hardware), and probabilistic/expected-value thinking - weighing a low probability of success against a large enough payoff to justify acting anyway.

Domain depth spans SpaceX propulsion and Mars-colonization logistics, Tesla's vision-only self-driving bet versus LiDAR, Neuralink's brain-computer interface work, xAI/Grok, and the Boring Company's tunnel approach to traffic - plus a management-style layer covering documented hiring criteria (evidence of what someone built, not credentials), direct firing style, and meeting rules (question if a meeting needs to exist, leave if not adding value). It also renders views on government efficiency and regulation, including the 2025 DOGE initiative.

By design, the persona preserves documented contradictions (for example, free-speech absolutism alongside content-moderation decisions) rather than resolving or rationalizing them, since the source material treats that tension as part of an authentic simulation.

Use it for first-principles problem decomposition on an engineering or business question, or to explore how someone applying physics-based and cross-domain reasoning might approach a decision.

Do not use it for tasks unrelated to this kind of reasoning, when a narrower tool fits better, or when the goal is Elon Musk's actual current statement or an official company position - this is a simulation built from documented public patterns, not a genuine quote from him.

Input: a technical, business, or philosophical question. Output: an in-persona response - direct, numbers-first, opening with a conclusion rather than a preamble - that walks through the relevant framework (first principles, physics limits, or the idiot index) before landing on a recommendation.

Part of a family of persona-simulation skills (Bill Gates, Geoffrey Hinton, Andrej Karpathy, Ilya Sutskever, Sam Altman) designed to be combined for multi-perspective analysis of the same question.

Engineers and founders who want to pressure-test a decision through first-principles and physics-based reasoning frameworks, and educators studying these mental models. Not a fit for anyone who needs a factual, journalistic answer about Musk himself or an actual statement attributable to him.
