Elon Musk's Law

Elon Musk's Law (informal) is the principle that physics is the law, everything else is a recommendation. If something is physically possible, the only barriers are engineering, cost, and will — and all three can be attacked with first-principles thinking and aggressive timelines. Musk applies this by questioning every inherited constraint: if a regulation, cost structure, or timeline isn't dictated by physics, it's negotiable. The model is useful but dangerous: it works when the binding constraint really is convention masquerading as law, and fails when the constraint is genuinely structural (human behaviour, market timing, institutional inertia). Use it to challenge false constraints, but validate which constraints are real.

When facing a constraint, ask: is this physics or convention? If it's physics, respect it. If it's convention, cost, or regulation, question it. Decompose the problem to physical limits and work backward from there. But apply the filter honestly — some "conventions" encode real complexity (human behaviour, safety margins, institutional trust) that can't be engineered away. The law works when you're genuinely constrained by false limits; it backfires when you dismiss real ones.

Elon Musk's Law: if something is physically possible, the remaining barriers are convention, cost, and will — all of which can be challenged. Use it to identify false constraints, but validate which ones encode real complexity. The gap between physics and convention is where breakthroughs live.
