I love how some folks are like "Elon isn't a real engineer !" and then he starts going on a tangent in the middle of a presser about how flanges are a PITA to seal once you exceed a few hundred bar (just over a few thousand PSI), and how welding improves the plumbing significantly. Like, what!? That's not how C-suite bigwigs talk. That's primo enginerd banter.

Which one of these personalities is he, when making statements about Tesla FSD? Edit: The answer to this question will be highly relevant during the lawsuits that will follow, the first time the Beta FSD kills somebody.

I think he's more in-depth about the rocket stuff than the Tesla stuff. He seems to exhibit more of the broad sentiments and more manager-esque talk when it comes to FSD.

I don't know how that plays into legal ramifications at all; I'm sure there will be the inevitable "well Elon said it can drive itself and make breakfast and solve P=NP!" but I have no clue if that carries any legal weight and frankly I don't care. He's a bit of a massive douche (no worse than bog-standard billionaires) but he has nerd chops and done a good job of hyping electric cars and space.

Honestly I kinda wish he'd just focus on the rocket stuff and lay off the FSD until it's a bit more mature exactly because of the media and lawyers chomping at the bit.

"It's gonna be cramped, dangerous, difficult, very hard work. You might die." -- Elon's sales pitch for Mars, in his own words. I wonder if any billionaire (or their children) will be doing the early work. It's an interesting game of "Who values their life the least?" knowing that their sacrifice will make for a better future. Of course, it's not a foregone conclusion that there will be a disaster. But over the cours…

Why do we need to fly 3 months to some inhospitable planet that is in worse condition than Earth would be (even after nuclear wars and global warming) to make progress? I suppose there's an idea we could apply everything done on Mars to Earth, but like... seriously, what we just took all the prep for mars and just put it in the middle of the Empty Quarter, the Saraha, Antarctica? People barely want to live in the arc…

Now that I think about it, we would get real good at settling desert and polar regions with the experience and data coming back from an established Mars colony. We could also learn more about more efficient habitation? Think of all the tech we have developed just for LEO (you know, like those listicles show) and imagine how much knowledge we would convert to use in helping everyday peoples' lives?

The basic idea is to not have all your eggs in one basket. We are one asteroid strike away from losing all human life on earth. Having 2 habited planets spreads the risk. Obviously having those planets in different solar systems would be even better, but we don’t have the technology for that, yet.

You're presenting a false dichotomy. Our options aren't only (a) live only on Earth, and (b) live on Earth and Mars and potentially other planets. There is, for example, (c) live in man-made structures orbiting the sun at a distance of 1AU, which is debatedly much more sensible than trying to live on Mars.

Hmm. With Starship's lifting capacity, that might become a side project. Maybe they could even sling something to become part of the orbital station and continue to Mars

This is the first time I’ve ever heard him speak. Is he always this awkward? Based off of the 5 minutes I watched, he clearly hasn’t gotten to where he is through charisma and public speaking skills. I’m just wondering if this is typical for him. Also, a million tons to Mars? If each starship lifts 100 tons, that is 10,000 launches. I think he said launch windows only come around every 2 years. He is either planning…

Launch windows for leaving Earth orbit come around every couple years. But most of that million tons can be lifted to orbit and assembled well in advance. It's only a relatively small weight which is perishable -- some food and a few humans.

He was born autistic.

One of the secrets about Musk is that he is actually a much better speaker when he just goes of on technical stuff like that. The problem with Musk is that when you ask him an even slightly open question, he always basically goes to the what he considers the fundamental answer. That's why so many of his answer are the same and people who know him well can already tell what most answers to most question will be. Howev…

Yep, I can really feel the friction from the gears in his head when he's trying to explain something at a general level, or express broad empty platitudes about space, electric cars, AI, or whatnot. That's something I've definitely struggled with, and also why I dig it when he shuts off the filter and starts talking about leaky flanges or deleting some crufty noise-absorbing padding that was the engineering equivalent of the parable of monkeys with a ladder. Like if I wanted to hear billionaires bloviating boring bullet points about business buzzwords, I'd listen to Bezos.

I have no opinion to express on Elon but I will say that I’ve heard non-technical managers lap up stuff like that in meetings with the engineers and then regurgitate it elsewhere. If I had to guess his technical competence is somewhere in the middle of the distribution of opinions on the matter. I’m sure he’s fine.

Sure but if you ever listen to his longer interviews, in particular those with Tim Dodd (Everyday Astronaut), it's very clear he has a deep understanding of rocket mechanics, production, logistics, launch pad development, etc. It's well beyond manager-just-regurgitating-stuff they hear. One interview he stops briefly and gets into some nitty gritty about hold-downs on the starship pad or something.

He also has a deep understanding of how important government assistance was to getting SpaceX where it is now but that hasn't stopped him from trying to stop others from benefiting from the same.

He shows a lack of rational thought in regards too SpaceX that is sometimes rather worrying. Take, for example, the time he smoked a blunt on camera which isn't exactly what one of his largest customers likes to see in their executives they are entrusting with launching one of a kind national security assets.

I'm glad SpaceX has an actual professional management team to run most day to day operations.
