#415 How Elon Thinks

What It Covers

Eric Jorgensen's book "The Book of Elon" compiles Musk's core mental models, engineering principles, and business philosophy drawn from years of interviews and writings. This episode walks through Musk's frameworks on first principles thinking, organizational design, manufacturing, hiring, and building companies that create measurable utility for humanity.

Key Questions Answered

• •First Principles vs. Analogy Thinking: When Tesla's battery costs were assumed fixed at $600 per kilowatt-hour, Musk broke down raw material costs on the London Metal Exchange and found the true floor was $80 per kilowatt-hour. For any entrenched cost assumption, decompose it to constituent materials or components before accepting conventional pricing as permanent.
• •The Five-Step Algorithm: Musk enforces a strict sequence across all his companies: delete dumb requirements, delete unnecessary parts or processes, simplify, accelerate, then automate — in that exact order. Reversing steps is costly; Tesla had to physically remove hundreds of robots through a hole cut in a factory wall after automating processes that should have been deleted first.
• •The Idiot Index for Cost Reduction: Calculate the ratio of a finished component's cost to its raw material cost. A high ratio signals manufacturing inefficiency, not material scarcity. Musk requires all engineers to know the best and worst parts in their systems by this metric at all times, using it as a continuous pressure mechanism against unnecessary cost accumulation.
• •Hiring by Character Proximity and Attitude Priority: Assess a candidate's character by examining who they voluntarily spend time with, since associates reveal what self-presentation conceals. Then prioritize attitude over existing skill, because skills transfer through training but attitude requires, as Musk puts it, a full brain transplant. Look for candidates already working on the mission before they applied.
• •Speed as Structural Advantage: A factory operating at twice the speed of a competitor is functionally equivalent to owning two factories. Musk applies this by eliminating large recurring meetings, requiring walk-outs when a participant stops adding value, and framing every delayed day at early SpaceX as forfeiting future revenue at a projected $10 million daily rate against a $100,000 daily burn.
