Comment Re:3D printing whole rockets was such a dumb idea. (Score 1) 47

Oh god. If I spent enough time digging through my ancient Slashdot posts, somewhere back there there are posts of me going, "While I loved the strategy behind Falcon 9, I'm really not keen on this plan to make Starship out of huge carbon fibre tanks, that sounds like a really failure-prone solution..." I'm glad they only spent like a year on that idea before deciding it was dumb; somewhere back there there's also a bunch of posts of me cheering their switch to steel ;) . SpaceX still keep having random COPV problems (most of which they don't even make themselves). Not too encouraging for the notion of the cold gas thruster add-on to the Roadster, where the plan is to replace the back seat with COPVs, so you have a COPV right behind your head.

Electron has been getting by on CF, and honestly I'm impressed, but they've also been only working with very small launch vehicles thusfar. We'll see how neutron goes...

Small difference: drugs are known to be harmful, and illegal. The harm of social media to developing children has only recently been documented

If it is known that social media harms kids, then doesn't the state share some of the blame? Why is there no law?
If it is not known (or only recently came to light), can you really blame the social media companies? You could blame them for trying to block relevant legislation, but not for harm done in the past.
If the harmful effects were known to the companies and they kept it quiet, then you'd have a case, morally speaking. Bit like the tobacco firms.

Comment Re:taxing unrealized gains is problematic (Score 1) 278

So how about closing that particular loophole, and make them pay capital gains on the profits that they do realize? For instance, by taxing such loans with no "normal" repayment schedule as dividend. We've had similar issues, with business owners borrowing money from their company with no intention of ever repaying it, thus avoiding dividend tax. A new law caps these "non market conformant" loans at 100k.

A cash grab like this is pretty sickening. Even in the rather socialist leaning country I live in, this would probably not stand, local courts and the ECHR might well consider similar taxes to amount to appropriation, and illegal.

Comment 3D printing whole rockets was such a dumb idea. (Score 1) 47

Don't get me wrong, there's a lot to say about printing small rocket parts, such as for the engines. But they were printing basically sheet metal cylinders, which is such an immensely slow and inefficient way to go about it, and it left them with parts that were heavier and less aerodynamic (rougher surface). Crazy that idea ever got any funding.

Comment Re:Anyway SpaceX is a huge scam so I suspect (Score 4, Insightful) 47

"SapceX has got to be a huge scam too" - SpaceX launches the vast majority of the world's commercial cargo to orbit. The Falcon 9 FT has the highest success rate of any rocket with a statistically significant number of launches under its belt, and is dirt cheap. SpaceX's core operations are roughly breakeven, but that's including subsidizing the development of Starship. Starlink is a money printer.

There are lots of things sketchy about the SpaceX IPO, to say the least, but SpaceX, as a company, has been extremely successful with rocketry.

The funny thing was that I knew him for like six months online before I realized he was fully paralyzed. He's been covered in the Finnish press a number of times. Amazing guy. Up until recently he was living in a house he built himself before ALS struck, but the medical service decided he was too far away and he had to move closer. You lose a lot of control over your life with ALS.

He wrote a book about nuclear safety engineering recently, which is a fascinating read, and which I strongly recommend.

Comment Re:How exactly does a 50% tax on stock value work? (Score 1) 180

I'm also not opposed to the idea. Not because of a supposed concentration of wealth. Musk does not have a trillion dollars, taken from elsewhere, sitting in a giant warehouse somewhere; it's all stock in a massively overvalued company that he built. His riches do not make us poorer. And I don't envy him his wealth, he's welcome to it.

What I do have an issue with, is the concentration of power this represents. Wealth, whether in actual dollars, publicly traded stock or private stock, represents an undue amount of influence in politics. If we're doing a tax on large companies, or a wealth cap, this would be the reason I'd agree with it. Not a sense of "fairness".

"OpenAI hasn't had their IPO yet, so couldn't they just find some kind of workaround to avoid this?"
Not necessarily. The tax could be paid in stock, in fact that would not be a bad idea. So that the control of important companies does not remain in the hands of a handful of individuals. Again, the only justification of this would be to prevent a concentration of power.

Motor neurons dying != brain control of motor neurons dies.

Anyway, you don't need a brain-computer interface for an ALS patient to work. I have a friend in Finland with ALS who works as a consultant on safety for a nuclear reactor startup (he was a nuclear safety engineer before becoming paralyzed). All it takes is an eye tracker.

The biggest problem is the typically short and unpredictable lives of ALS patients. He has lived abnormally long (I think something like 13 years now), but a large part of that is due to him thinking like a nuclear safety engineer (backup on backup on backup, training his nurses to have zero tolerance for error, etc), and still has a close call like once per year or so, and I regularly worry when I don't see him online in a while that something happened that killed him. A tube comes off a life support system. A nurse forgetting to reconnect something. A mucus plug in his airways. Etc. ALS patients' lives are fragile. He does CAD design for parts on his computer (it's too hard to do it with the mouse using the eye tracker, so he designs the shapes programmatically) and orders them 3d printed to correct any deficiencies he finds in his support systems.

ALS patients also have to constantly fight the medical system. Even in a place like Finland that will actually do long-term care for ALS patients (which is very expensive), it shows that it would be much more convenient for them if those danged ALS patients would choose to die (and there's often pressure put on them to do so). One of my friend's goals is to outlive a doctor who told him he would only live a year or two put a lot of effort into getting him to choose death. It was a battle to get long-term ventilator care. It was an even bigger battle to get to use a cough machine and to be able to control the settings on it; without regular, meaningful cough support, your lungs fill with mucus, and you'll probably eventually die of a mucus plug, pneumonia, or whatnot.

By contrast, ALS patients today can actually live a decent life using eye trackers. It's not like before when you had to tediously spell out things one character at a time to a helper holding an E-tran frame. Given that 1 in 500 people will get ALS at some point in their life, we really should be allocating a lot more money toward researching cures, even if purely from a cost-saving perspective.

(One final note: if anyone here starts getting peripheral weakness and worries its ALS: your instinct will be to exercise more. Do just the opposite. If your peripheral neurons are dying, the last thing they need is more work. ALS overwhelmingly strikes active people - one researcher I was reading noted that in her entire career, she's never met a couch potato who got ALS. Take it easy, see a doctor immediately, and if it is ALS, start preparing early, but know that you do not have to be forced to choose to die, so long as you can get care. You can live a decent, productive life if you choose to).

Comment Re:The SpaceX Valuation is Insane (Score 1) 67

Not just "the future", but the future of AI. If you go by future projected revenue as predicted by SpaceX (which is the only projection that justifies their valuation), they are an AI company with a small space division. An AI market in which they are not at all well-positioned. Buying Cursor may improve that somewhat. Maybe that's the plan - buy every promising AI startup with stock, until they hit gold.

Comment Re:Antropic literally asked for this (Score 3, Interesting) 40

Whether Anthropic was trying to hype about Mythos / Fable or not (and FYI, it is a pretty big leap forward), they absolutely did not want to get public access shut down. The US government very much seems to want to have exclusive access to it for now.

Also, to clarify the "jailbreak": They took open source projects that had known vulnerabilities, as well as deliberately introducing vulnerabilities into some other projects, then asked Fable to fix them, and then asked for test scripts to demonstrate that the exploits could no longer be exploited - the implication being that they could then use those exploits against unpatched systems. But what's the logic here? The challenge isn't "how to write exploits against known bugs", any model can do that. The challenge is finding the bugs - something Mythos / Fable has proven better than previous models at. Even if Fable refused to write said test scripts, it would automatically downgrade to Opus 4.8, and then *Opus* would have written those test scripts. Or any other model out there could do it, including free open source ones that can be safety-abliterated at will.
