Didn't SpaceX stop streaming their launches?

I wouldn't notice. I stop watching them, because they got boring . Let me say that again: space launches got boring . I hoped, but never believed, I'll live long enough to see this happen.

That's nonsense. Sure Psyche has a lot of valuable materials on it, but so do mountains on earth, doesn't mean its great way to make money. There are things far closer to earth that are far easier to get to, and those things are also far smaller then Psyche and thus far easier to mine. The most serious space mining company right now is targeting near earth asteroids for platinum group metals.

Heavy elements like gold and platinum sank to the center of the earth's core while the whole planet was molten and this is why they are rare near the crust. Asteroids have never been entirely molten, and as such have valuable heavy elements dispersed relatively evenly throughout. In other words, much higher concentrations of valuable elements are expected to be available much closer to the surface of asteroids than o…

I know but that doesnt change what I said.

Elon bringing excitement to the human race. His way of pushing through is something that gives me hope in the capabilities of humanity.

>pushing through It's basically still the same technology as the first rockets, just bigger. We have more and cheaper satellite launches, but we're not really any closer to colonising space. That's Musk's trick, selling revolution, delivering evolution.

SpaceX is number one, you belittle incredible accomplishments across the board. If it’s so easy, why didn’t anyone else do it at this pace/scale? Why doesn’t anyone else do it at their scale today?

The hardest thing to achieve is delivering when anyone has access to the same technologies, resources etc. He delivered, the others didn’t. Especially NASA, by comparison.

Be fair and give the man the props where the props are due.

The engineers who build the rockets, and they didn't succeed and anything impossible. Building landing rockets was thought to be too expensive not impossible. Why is Tesla's FSD still not working? Wasn't Musk around? The Spaceship is also nothing impossible, let's wait for his Mars colony.

If it’s all so possible, how come SpaceX has no viable competition? I get it, you don’t like Elon, that’s understandable, but let’s please give adequate credit where credit is due. Pulling off just one of the things he did would be a monumental achievement for anyone. He’s done what at this point, 3-4? Does that really mean nothing to you just because you don’t like that he has the gall to use the First Amendment?

Did Pope Julius II pull of the frescoes of the Sistine Chapel?

I get it that Musk was necessary to get the money but money doesn't build rockets otherwise Bezos company would have succeeded too.

Seems like the actual engineers are the ones to praise.

Musks seems more like the type who has read a sci-fi book or seen a movie and has enough money to pay people to build what he has read or seen.

The problem is that he often underestimates the technical challenges. This sometimes works when the problem only needs an evolutionary step, like landing rockets, but fails when it comes to revolutionary discoveries.

The whole Twitter thing is only accelerating the destruction of his nimbus.

When he makes announcements and promises, I now always hear in my head: "Monorail, monorail"

Also, wont it theoretically speed up and decrease international shipping + travel. We should be able to go from the US to Japan in an hour or two in the future.

Maybe. The fundamental physics involved in suborbital flights mean that you are likely experiencing sustained acceleration of 3+ Gs minimum. That is a lot, something near the max g force of a roller coaster but lasting for minutes. Combine that with the launch/landing zones needing to be many miles from anything, and it isn't really ready for primetime. Just for reference 1.3 Gs is the max sustained load you will fee…

If you’re a military unit about to get wiped out by an enemy force due to running out of ammo, I imagine getting 100 tons of ammo in 1 hour vs in 19 hours would be a big difference?

Even SpaceX's methods of fail fast (and often explosively) is relatively cheap. SLS is doing it the hard and expensive way.

The downside is that rapid iteration doesn't always give the same insight in terms of scientific understanding. E.g., Design_A fails. We quickly pivot to Design_B, which works. However, we don't spend the time ultimately understanding why Design_A failed. This can be operationally great, but it can also risk conflating being lucky with being good. If you don't fundamentally understand why the thing failed the first t…

Luck tends to average out over many trials.

Some counter-points:

1) The failures themselves aren't all too complex (relatively speaking), and by the time the design made it to a flight vehicle it has been vetted for all immediately knowable risks. The rest you discover during flight. And even then the actual nature of the problems rarely (if at all) are esoteric or present breakthrough scientific discoveries.

2) Failure in rocket launches are catastrophic leaving behind very little evidence. There could be a limit to how much you can learn. But...

3) ...SpaceX is a business serving customers, and if a pivot means going away from a complex cloud of possible failures (known and discovered) to more robust, more deterministic, more reliable, you should do it.

4) At what level do you stop and go "this is fundamental enough"?

Name any private individual who has done more for the defense of Ukraine then Musk. Suggesting that a civil war will end in a cease fire along battle lines is a very common way for civil wars to end. Even if during those wars both sides absolutely are convinced that they will have total victory.

Name any private individual who has done more for the defense of Ukraine then Musk. Irrelevant to the fact he went on to also blatantly dick the Ukrainians over in late 2023.

Wow how grateful. In objective reality he helped Ukraine a huge amount and thus is clearly very pro Ukraine. Ukraine should literally be thanking him everyday. But I guess that is totally irrelevant. What have you done for me lately asshole.

Frankly I think the way they treat him is ridiculous. A media discord based on bad and inaccurate information heavily biased reporting somehow making him out to be the bad guy.

Ok got it. Makes total sense. War really makes people lose touch with reality.
