Walter Isaacson explains exactly how Elon Musk uses first principles thinking to build rockets: When young Elon wanted to send people to space, he first tried buying used rockets from Russia. They jacked him around - it didn’t work So he went back to first principles. He asked: Exactly...

Elon Musk breaks down the first-principles math that told him rockets were massively overpriced "How much should a rocket cost? The typical approach people take is they look historically at what rockets cost and assume any new rocket must be similar to the prior cost" "A first-principles approach: you look at the materials the rocket is made of. Aluminum, copper, carbon fiber, steel. What are the constituent elements, how much do they weigh, and what's the material price per kilogram? That sets the actual floor on what a rocket can cost" "Then you realize the raw materials of a rocket are only maybe 1 or 2% of the historical cost of a rocket. So the manufacturing must necessarily be very inefficient"

SpaceX had zero idea how to build a rocket in the beginning. That became the genius of it: Elon rejected conventional wisdom entirely and grounded everything in first-principles thinking instead of copying competitors or blindly following “best practices” nobody could justify. Tesla and SpaceX exist because he refused to accept that this is just how things are done. But the cost is real. ELON CLIPS

Elon Musk on how he learned how to build a rocket company: “I read a lot of books” Elon is asked how he acquired the expertise to be the CTO of a rocket ship company. He replies: “Well, I do have a physics background. That’s been a helpful foundation. Then I read a lot of books and talked to a lot of smart people.” “You’re self taught?” the interviewer asks. “Yes, I don’t have an aerospace degree,” Elon responds. “How did you go about acquiring the knowledge?” the interviewer asks again. Elon replies: “Like I said, I read a lot of books, talked to a lot of people, and have a great team.”

Elon Musk explains how to get startup ideas When asked how he comes up with startup ideas, Elon responds: “I tend to think of things from a sort of physics standpoint… what’s the best way to accomplish something? And then pursue that. That’s also a good way to determine if something’s far from its optimum.” He gives rockets as an example: “You could reason by analogy and say the rocket is going to cost a certain amount because that’s what prior rockets have cost. Or you can say, well, what is a rocket made of? What are the material constituents? What do they weigh? What’s the cost per unit mass? And that sets the limit asymptotically for what a rocket can be. So if you can figure out some creative way to rearrange those elements into a rocket shape, then you can achieve a much better outcome.” He also thinks combining ideas from different industries is really helpful for innovation: “What have people discovered in one industry and can that be applied to other industries? That’s I think also a great source of ideas. But usually you just struggle on a solution and try a bunch of things. Most of them don’t work and occasionally one does.” Source: VANITY FAIR (Oct 2014)

Walter Isaacson: If you don't want Elon Musk to control so many industries, you should learn to get stuff done too. “Why is Elon successful at some of these things, like getting 5,000 satellites up? He said we used to be a nation of really great risk-takers. Even the people who ran Boeing probably were risk-takers at one point. Not safety risks, but they were going to try rockets. He said everybody who came here, whether it was on the Mayflower or across the Rio Grande, they were adventurous, they took risks. He says nowadays we have more referees than we have risk-takers. We have more regulators than we have innovators. We have more people saying you can't do it, the lawyers, the whatever. He said it's made it so that our big military contractors can't get anything done. We can't get high-speed rail. I would think that the best way to make sure he doesn't have so much clout on things is for somebody to be able to build more electric vehicles. He built a charging network and then the US Government, Ford, GM, decided to build their own, and they've surrendered because the Tesla charging network works. I'm not trying to just sing his praises, but it would be useful if you don't want him to control the charging network in America, if you don't want him to control the Internet in outer space, if you don't want him to control rocket launches, to have Boeing and Northrop Grumman and others be able to get stuff done.” The 92nd Street Y, October 13, 2023

In 2002, Elon Musk tried to buy a rocket. The Russians quoted him $8 million per unit. American aerospace companies wanted over $65 million. He walked away from both. On the flight home, he opened a spreadsheet and broke down the raw materials. Aerospace-grade aluminum. Titanium. Copper. Carbon fiber. He priced each on the commodity market. The total came to roughly 2% of what the industry was charging. That gap is what first principles thinking actually looks like. Not "how do we negotiate a better deal." Not "who else sells rockets." Just: what is this thing actually made of, and why does it cost what it costs? The answer was overhead. Legacy processes. Layers of contractors and subcontractors. Margins stacked on margins. Nobody had questioned the price because nobody had questioned the structure. Musk decided to build it himself. The first Falcon 1 exploded 33 seconds after launch. The second made it further but failed to reach orbit. The third exploded too. Three rockets. Three failures. SpaceX was almost out of money. Musk put his last $35 million into the company. If the fourth launch failed, that was it. September 28, 2008. Falcon 1 Flight 4 reached orbit. First privately developed liquid fuel rocket to ever do it. Seven years later, they landed a booster back on Earth for the first time. Now they do it routinely. The cost per launch dropped from $65 million to under $3 million for a reused Falcon 9 booster. Everyone else was reasoning by analogy: rockets are expensive because rockets have always been expensive. Musk reasoned from atoms: rockets are expensive because nobody rebuilt the system from the ground up.

Elon Musk: I started reading about rockets to understand why they're so freaking expensive. “I started reading quite a bit about rockets to try to understand why they're so freaking expensive. Where does the $60 million go for the Delta II? Now Delta II, I think, is $100 million or something, some crazy number. And Delta II is a relatively small rocket. If you go to one of the bigger rockets, it's anywhere from $200 to $400 million. Anyway, so I came to the conclusion that there wasn't really a good reason for rockets to be so expensive, and that they could be a lot less. Even in an expendable format, they could be less. And that if one could make them reusable, like airplanes, then the cost of rocketry would drop dramatically, the cost of space travel would drop dramatically. Because the cost of the fuel was maybe anywhere from 0.2% to 0.5% of the cost of the rocket. It's like a plane. How much is the cost of the fuel in the plane versus the plane itself? It's at least a two-order-of-magnitude difference. But nobody had really been able to make a reusable rocket work. So I thought, if we can do that, then that would really be the key breakthrough for space travel.” Interview at the Computer History Museum, 2013

ELON: SOMEONE HAS TO SOLVE ROCKET REUSABILITY — WHETHER IT’S SPACEX OR SOMEONE ELSE “The cost of the fuel and oxygen on a Falcon 9 is 0.3% of the cost of the rocket. So, it's a very tiny number. It's very similar to an airplane. How much does it cost to fuel up an airplane, and how much does it cost to buy an airplane? They're very different things. If humanity is ever to expand beyond Earth and establish a self-sustaining base on another planet, it's critical that we solve this problem. Whether it's SpaceX or someone else, someone has to solve the problem, and we can have a hundred-fold reduction in the cost of spaceflight. That's what SpaceX has been trying to do, and really that's been the goal since the beginning of the company. So far, I've not been very successful in that regard, but I think we have a handle on it. We've got a design that closes in the simulations. If we can build that thing, it should work.” Source: SXSW, March 2013

Elon didn’t start SpaceX to build a rocket company: “The original vision for SpaceX was not to start a launch company. Elon’s original goal was to increase NASA’s budget, and he was willing to just burn 100 million dollars on a philanthropic mission to display a greenhouse on Mars. Shooting a greenhouse to Mars with existing rocket technology, get this photo on the front page of every paper. A little plant on the red planet, the first time life had transferred to another planet. That’ll probably increase NASA’s budget and spur this wave of exploration and interest in space. When he tried to do that, he discovered that the space launch market was so expensive and un-innovative and hadn’t been moving forward. That’s actually how he discovered the opportunity to start SpaceX. That’s what’s actually going to move this market forward.”

Elon Musk explains his idea generation process in 2 minutes: "I tend to think of things from a physics standpoint, from a first principles standpoint. What would be the best way to accomplish something? And then pursue that." Elon explains how this reveals hidden opportunities: "That's also a good way to determine if something is far from its optimum. On rockets, for example, you could reason by analogy and say the rocket's gonna cost a certain amount because that's what prior rockets have cost. Or you can say: What is a rocket made of? What are the material constituents? What do they weigh? What's the cost per unit mass? That sets the limit asymptotically for what a rocket can be. So if you can figure out some creative way to rearrange those elements into a rocket shape, you can achieve a much better outcome." He shares a second source of ideas: "Combining ideas from different industries is really helpful for innovation. What have people discovered in one industry that can be applied to other industries? That's a great source of ideas." Elon also explains why he started with software: "The great thing about software or anything which just involves intellectual capital is that you and a few friends can just do it. That's why doing some sort of internet thing is great as an initial company. That's why Zip2 and PayPal gave me the capital to attempt more capital-intensive activities." He concludes: "Usually you just struggle on a solution. You try a bunch of things. Most of them don't work. Occasionally one does."

Lex Fridman asked Elon Musk what the meaning of life is. His answer was not what anyone expected. We do not know, he said. And that is exactly why we need to expand consciousness. Not to find the answer. To ask better questions. He believes the universe is full of things we cannot even formulate yet. We are like children trying to understand calculus. The problem is not that calculus is too hard. The problem is that we have not developed enough to know it exists. Consciousness, to him, is a tool for exploring the universe. The more of it we have, the better our questions become. The better our questions become, the closer we get to understanding what any of this means. This is why he builds rockets and brain interfaces and AI. Not because he has the answers. Because he thinks the only way to get them is to expand what we are capable of thinking. Most people spend their lives looking for meaning. Elon is building the tools to look for it at a scale we cannot yet imagine.
