One of the consistent patterns in how Musk builds companies is an impatience with anything that remains theoretical. SpaceX built a rocket. Tesla built a car. Neuralink implanted a chip. Boring Company dug a tunnel. In each case, the earliest physical version — however crude, however limited — was prioritised over additional planning. This is not recklessness. It is a recognition that the knowledge produced by building a real thing, even an imperfect one, exceeds the knowledge produced by planning to build it. Problems that are invisible in a plan are immediately visible in a prototype. Assumptions that seem sound in a presentation are tested immediately by reality. For builders with limited capital: the earliest physical, built version of your idea is your most powerful investment, regardless of how rough it is.
