Maybe space resources can help Earth survive. But, like the Polynesians who settled the Pacific, that's really not the primary reason humanity wishes to explore & settle this new ocean, the depths of space. (Quote below is from Christina Thompson's excellent book Sea People.)

"...Occasionally, there is famine or some other type of trouble, but usually it is a matter of chiefly ambition or pride." (Important. I've often been told the reason Polynesians explored & settled the Pacific is a desperate need for resources. Polynesians' own stories disagree.)

The Jones Act is the bedrock of the U.S. maritime and shipping industry.
@TransportDems are protecting American-made ships and jobs as costs continue to rise from the Administration’s war with Iran.
Community note
The U.S. ship building industry is “near collapse” according to the GAO, despite the Jones Act being in place since 1920.
Today, U.S. ships cost 5x as much as foreign ships.
U.S. flagged commercial ships declined 94% from 1960-2025, while the global fleet doubled.

I asked Grant to make this for me, and he did. Now I made like a rocket engine chamber thing, saved it as a STEP file, and am printing it as we speak. You literally can just vibecode your own CAD program now. Or you could, until they took Fable from us 😭 But sure, AI is useless
So when Fable was still available I used it to implement this basic CAD program in ~3 hours.

There was once a that socialism would work better than capitalism. This was mostly wrong and post-1989 it seemed like we'd agree on market economies plus a welfare state.
But an injection of green degrowth has birthed "socialism will wreck the economy — in a good way!"

I think Jared is always down to have open forum discussions like this because he’s so continuously locked in with NASA’s and contractors state of affairs.
I’d be shocked if he has to do homework before a speech. He just genuinely loves what he’s doing for our country.

Thank you for your work at Starship. I showed this to my 11 year old and 5 year old boys, both love Starship. I told them these are the guys building our multiplanetry ride.
You’re building future …
You’re building our destiny …

This will cause an incredible amount of misery for a lot of people. “But I’ll find my meaning in other ways.” OK? Like be top 1% of your job? A gamer community? Politics? Throughout history of humanity, the most scalable way to achieve a meaningful life is children. & most do!
Something is going on with American teenagers
Only 67% of liberal-identifying teens say they want at least one child, compared to 90% of their conservative peers.

Maximum of 25 satellites per year, experts say.
The aloof dismissiveness of the traditional aerospace contractors 12-15 years ago, man. They got absolutely bodied by SpaceX.

This was absolutely diamond hard no BS straight fact-spitting in the 20th Century. It was pure, hard-won, no bullshit wisdom.
It's an extremely good mile marker for how radically and singularly SpaceX changed everything.

We've transferred fuel and oxidizer in space through docking interfaces. We've transferred cryogenic liquids in space (just not propellants). We've demonstrated settling of LH2 and LOX in space and propellant acquisition in zero-g. Essentially we've done everything but put all the pieces together.

Let’s take a look at the performance of ArianeGroup vs the “dream” of SpaceX after that 2013 conference:

"What if it does?" is a question everyone should be asking right now.
A lot of American space execs had a similar attitude. They'd say, high on copium, "There's no way that SpaceX is going to achieve that launch rate or be reusable." And I'd say, "But what if he does?" Just deer in the headlights look.
