Elon Musk on engineering pitfalls (2019 Starship interview): • If a design takes too long → the design is wrong. Simplify, delete parts & processes. • Never fall for sunk costs — switch paths fast (e.g., carbon fiber → steel). • Everyone must act as “chief engineer” & understand... show more

🇺🇸 ELON: STOP TRYING TO OPTIMIZE SOMETHING THAT SHOULDN’T EXIST “Everyone’s been trained in high school and college that you answer the question — convergent logic. You can’t tell the professor 'your question is dumb' or you’ll get a bad grade, you have to answer the question. So everyone, without knowing, basically has this mental straight jacket on and they’ll work on optimizing the thing that should simply not exist.” Source: Startup Archive, Everyday Astronaut

This is how a top designer at Wealthsimple uses Claude Design for high fidelity prototyping. He always starts with the ask user question tool in Claude to transfer all the design details in his head to the model for additional context. 👀 Full convo on Sneak Peek: Danny Williams shows how he uses Claude R Perrin design for prototyping at Wealthsimple👇

Elon Musk says steel killed carbon fiber on Starship at one-fiftieth the cost. Carbon fiber was supposed to be the future of rocketry. Lighter than aluminum. Stronger than steel. Trusted by every Formula 1 team. SpaceX picked it for Starship. "Particularly if you go for a high-strength specialized carbon fiber that can handle cryogenic oxygen, it's roughly 50 times the cost of steel." Then progress stalled. The autoclaves needed to cure the resin had to outsize every autoclave on Earth, and the team couldn't even produce a clean barrel section without wrinkles. Musk, watching the Mars timeline slip: "At this rate, we're never going to get to Mars. So we've got to think of something else." So he asked the question nobody at SpaceX had asked: "What about steel?" It became known as the **cryogenic stainless flip**. Musk, who had already shipped Falcon 9 in aluminum-lithium, broke with the textbook. "When you look at the material properties of stainless steel, full-hard, strain hardened stainless steel, at cryogenic temperature the strength to weight is actually similar to carbon fiber." Starship ran on cryogenic methane and oxygen. The airframe lived at temperatures that flipped steel ahead of carbon fiber. "You could smoke a cigar while welding stainless steel." After Musk made the call, steel weighed less than the carbon fiber version. Fifty times cheaper in raw material. Twice the heat tolerance. Half the heat shield mass. Musk, looking back: "In retrospect, we should have started with steel in the beginning. It was dumb not to do steel." What "obvious" material in your work is silently costing you the project?

Elon Musk’s Elon Musk first principles algorithm: “Well, it's easy to say simplify and it's very difficult to do it. You know, I have this very basic first principles algorithm that I run kind of as a mantra, which is to first question the requirements, make the requirements less dumb. The requirements are always dumb to some degree, so you want to start off by reducing the number of requirements. And no matter how smart the person who gave you those requirements, they're still dumb to some degree. You have to start there because otherwise you could get the perfect answer to the wrong question. So try to make the question the least wrong possible. That's what question the requirements means. And then the second thing is to try to delete whatever the step is, the part, or the process step. It sounds very obvious, but people often forget to try deleting it entirely. And if you're not forced to put back at least 10% of what you delete, you're not deleting enough. And it's somewhat illogical, people often, most of the time, feel as though they've succeeded if they've not been forced to put things back in. But actually, they haven't because they've been overly conservative and have left things in there that shouldn't be. And only the third thing is to try to optimize it or simplify it. Again, these all sound, I think, very obvious when I say them, but the number of times I've made these mistakes is more than I care to remember. That's why I have this mantra. So in fact, I'd say the most common mistake of smart engineers is to optimize a thing that should not exist.”

"The one thing that's going to be truly future proof is judgment. What is the biggest challenge when you have a thousand AI engineers writing code? AI slop. In an era when you can do everything, the question is which of these things matter. On the engineer side, it is evaluating the code. Which of this code is even valuable? You can have AI engineers writing beautiful code that could be wrong, that could have bugs in it, that could be vulnerable. Someone needs to review it. Make sure to have a human review at some point, especially critical code that is in the core of your system. On the product side is judgment around what needs to be built and evaluating. And similarly in design, you have to have judgment around, does it make sense in the broader design system. I think this judgment is the number one thing that humans are going to bring in an era of infinite productivity."

ELON'S POV ON THE MEANING OF LIFE: "IT'S ABOUT THE QUESTION, NOT THE ANSWER" Elon is literally saying the entire purpose of human existence, and everything he's building, from Neuralink and Starship to Grok and Optimus, is aimed at one goal. What's the goal, you ask? To turn humanity into a massive superintelligence that can finally figure out the right questions to ask reality itself. "Humans are 30~40 trillion cells, trillions of synapses… but the why of it is just so we can increase our understanding of the universe. I came to the conclusion, Hitchhiker's Guide to the Galaxy style, that the answer is 42, but the real problem is we don't even know what the question is. The hard part is the question, not the answer. And for that you need a much bigger computer than Earth. So by expanding the scope and scale of consciousness, we can better understand what questions to ask about the answer that is the universe." He's literally saying the entire purpose of human existence, and everything he's building (Neuralink, Starship, Grok, Optimus), is to turn humanity into a massive superintelligence that can finally figure out the right questions to ask reality itself. Not to get the answer. To learn how to ask the question that makes the answer meaningful. This is why he doesn't give a damn about money, politics, or fame anymore. He's playing the longest game in history: Turning consciousness into a galaxy-scale instrument so we can finally understand why anything exists at all. Source: Nikhil Kamath, Elon Musk

Elon Musk explains his 5-step algorithm for solving any problem: "The most common mistake of smart engineers is to optimize a thing that should not exist." "I have this very basic first principles algorithm that I run as a mantra." Elon breaks it down: Step 1: Question the requirements. "Make the requirements less dumb. The requirements are always dumb to some degree, no matter how smart the person who gave you those requirements. You have to start there, because otherwise you could get the perfect answer to the wrong question." Step 2: Try to delete it. "Try to delete the part or the process step entirely. If you're not forced to put back at least 10% of what you delete, you're not deleting enough. Most people feel like they've succeeded if they haven't been forced to put things back in. But actually they haven't, they've been overly conservative and left things in that shouldn't be there." Step 3: Optimize or simplify. "The most common mistake of smart engineers is to optimize a thing that should not exist. So you don't optimize until after you've tried to delete." Step 4: Speed it up. "Any given thing can be done faster than you think. But you shouldn't speed things up until you've tried to delete it and optimize it otherwise, you're speeding up something that shouldn't exist." Step 5: Automate. "And then the fifth thing is to automate it." Elon explains why the order matters: "I've gone backwards so many times where I've automated something, sped it up, simplified it, and then deleted it. I got tired of doing that. So that's why I have this mantra."

If you're drowning in bureaucracy at work, your company probably isn't following Elon Musk's five-step process for improvement. Here are the highlights: "Everybody's been trained in high school and college that you have to answer the question. It's convergence logic. You can't tell a professor '"your question is dumb" or you'll get a bad grade. You have to answer the question. So without knowing it, people have mental straight jackets on. They will work on optimizing the thing that should simply not exist." "It's particularly dangerous if the smart person gave you the requirements because you might not question them enough." "If you're not occasionally adding things back in, you're not deleting enough process. The bias tends to be very strongly towards adding things." (These quotes are paraphrased to make them easier to read).

Engineers and salespeople think in completely different ways. - Engineers: "If you ask them a question, a hundred percent of them will try and think of what is the correct answer to that question." - Salespeople: "If you're a salesperson, your first thought isn't: what's the answer? It's: why are you asking me that question?" "And so if you have an engineer talking to a good sales guy, it's going to upset them. Because they're often not gonna answer the question." "The guys who are good at the job get rejected, because you don't like them. And then the people who are terrible at it, those are the ones that ended up getting hired." "These CEOs just wanna take a guy who failed the engineering test, put a clean shirt on him and make him the head of sales." benahorowitz.eth with Brian Halligan

Does anyone really think that Elon Musk runs SpaceX, Tesla, Neuralink, Twitter/X etc., spends '80 percent of my time designing, engineering and manufacturing', while scattergun posting on Twitter/X every day at all hours? Who REALLY controls these companies is a question worth asking. At the same time he flies around meeting world leaders who supposed not to like his platform 'disinformation' yet drool over him, even interview him like Sunak, and promote him for propaganda like Netanyahu. Here Musk-groupie Joe Rogan buys the lie that all of the above is true, that Musk is a genius, and likens him to an 'alien'. It is not possible to do all of these things - and more - at the same time and he obviously doesn't. It's all part of the making of the myth that is Elon Musk. The question is why? The answer will be clear in due course.

“Working at SpaceX is like being dropped into a zone of shocking competence. Everybody is ultra competent and the reason everybody is ultra competent is because if they're not Elon Musk sniffs it out and fires them. Elon knows because he's talking to the people actually doing the work. At this point having done this for 25 years he can sniff this out really quickly. The best engineers in the world want to work for him because he's the one CEO who’s able to work with them as a peer on whatever the technology is. What would be better as an engineer than being able to design a rocket engine with Elon Musk as your engineering partner?”

I honestly do not need to campaign for our Premier, he is going to remain our Premier with Ashton Hurn as opposition. I watched this video absolutely frustrated. Don’t ask a question and continually interrupt that person while they answer your question. If you do this, you instantly give me the impression that you’re arrogant. It’s one of my biggest pet peeves in politics. I want to hear the answer. We all want to hear the answer, from all sides.

SCOOP | Abdul El-Sayed, the far-left Democratic candidate for Michigan’s Senate seat, said at an event with Jewish supporters last week that he struggles to answer questions about whether he believes Israel has a right to exist as a Jewish state. “I often struggle with the question that people ask in this particular scenario, because what they now ask is, ‘Do you believe in the right of Israel to exist as a Jewish state,’ which, to me, forces the question of a definition of what a Jewish state means.” Read the full story from Marc Rod:

A veteran yelling “I went to war for a First Amendment zone?” is exactly why I ask people in power the questions I ask. Because if the Constitution is sacred enough to draft someone’s kid for, it should be sacred enough to uphold when people protest at home. They may dodge the answer. But they heard the question, on the record. Elon Musk for someone who cosplays as the First Amendment’s divorced dad, you are awfully quiet when actual people are being told where their speech is allowed to stand.

Elon Musk clearly explains why Grok must be maximally truth-seeking: “I think you want Grok to say things that are true, even if they’re not politically correct” Focus on cogent reasoning - make sure axioms as close to true as possible, no contradictions, and conclusions that necessarily follow with the right probability. It’s just critical thinking 101 The proof is in the pudding: For any AI to discover new physics or build technology in reality that actually works... there is BS physics, you have to be extremely truth-seeking Physics is the law. Everything else is just a recommendation. If your rocket design is wrong, it blows up. Reality doesn’t lie
