Ehsan's Insight

First principles thinking — reasoning from fundamental truths rather than by analogy — is Elon Musk's most cited mental model and the hardest to practice. The reason: analogical reasoning (copying what worked for someone else) is 10x faster than first principles reasoning (deriving the answer from scratch). For most business decisions, analogy is appropriate and efficient. First principles is worth the cognitive cost only when existing approaches are clearly not working or when a technology change has invalidated old assumptions. AI is a genuine first-principles moment for content creation, customer support, and software development because it changes the fundamental cost structure. Applying old assumptions about headcount, timelines, and budgets to AI-enabled workflows produces wrong answers. Rebuild the math from scratch.
