matthewdgreen··on AI boosts research careers but narrow the span of ideas explored: study
It's a little more complicated than that. If all you're interested in disovery, you can wander off into rabbit holes or disappear into areas that are only interesting to you. Publishability is useful because it gives you useful external feedback into whether a community thinks what you're doing is "worth discovering". Like any metric, you can find yourself gaming it (intentionally or unintentionally) and it has a slew of other failure modes. Still, you can prize discovery and also care about what other people think.

Wouldn't be bad if the product hadn't been paid for in advance. If it can't be delivered in working form for this car, that's not the end of the world. Tesla can just refund the undelivered product, with interest.

I paid for a car that drives itself in 2018 and I haven’t received it. Any updates?
matthewdgreen··on EU now one step away from reviving private message scanning rules
I know a number of people who have gone down this route, including Senators. For example, here's Senator Wyden's proposal to add $5 billion in mandatory funding to investigate and target sexual abusers [1]. The problem with these efforts is that they're expensive: fighting child exploitation requires enormous amounts of funding.

Guess what doesn't require billions of dollars? Mandatory scanning paid for by tech companies, followed by dumping the billions of hits they produce [2] on overworked police and clearinghouses that mostly ignore them.

matthewdgreen··on The classifiers Anthropic puts in front of Fable are too zealous
As a related note: The only way a consumer can get ZDR protections for Claude or OpenAI is to use Amazon Bedrock. But as you say, doesn't work for Fable. I think it even requires approval for anything past Opus 4.6.
matthewdgreen··on Fable is not a useful model
We don't need top-end frontier models to write simple applications. Opus works very well for that and it's cheaper. We need them to write things that are at the frontier.
matthewdgreen··on The classifiers Anthropic puts in front of Fable are too zealous
I'm working on cryptography, all from academic research papers. Started well, but it eventually got some word into its context that is on the banlist. I found that if you tell it to fire off clean Fable subagents and you instruct it to check the Claude Code billing data to check for downgrades, you can get most high-sensitivity spec/review tasks done with Fable. Most.

I figure that once GPT 5.6 comes out, Anthropic will become interested in making the safety gate non-destructive.

matthewdgreen··on China sentences official to death for taking $325M in bribes
We improve it by ensuring the same people don't dominate the justice system and that prosecutions still happen whenever they don't. It was Biden's and his AG's job to do something about this and he fumbled.

What specs do you require for long-distance train electrification vs. the specs you need for electrical delivery to the grid?
matthewdgreen··on “Beyond the limit”: Satellites and mirrors in space pose threat to the night sky
Even Star Trek admits that there are horrible events that lie between our world and the utopia.
matthewdgreen··on “Beyond the limit”: Satellites and mirrors in space pose threat to the night sky
I didn't understand what these satellites were really like until I visited Zion National Park two weeks ago. Zion is an International Dark Sky park, and so I was really looking forward to seeing the stars. Instead we sat outside and watched dozens and dozens of fast-moving stars zip around on all sorts of trajectories. I'm not saying it ruined the experience (I'm not an astronomer, and it was kind of fun.) But it really brought home how fundamentally we've changed the sky. I also hope we're able to lay enough fiber in developing countries that this many satellites don't need to stay up there forever.
matthewdgreen··on Soatok's Informal Guide to Threat Models
There's a lot of stuff in this post I agree with. There's also a lot of stuff that hints that the author doesn't believe in the worst case they name: that there might be a classical cryptanalytic attack on ML-KEM that occurs before Q-day.
matthewdgreen··on Supreme Court upholds broad conception of birthright citizenship
Sure, I already did explain it. They explicitly said that "not under the jurisdiction" would cover children belonging to Indian tribes, the children of ambassadors, and they discussed the need to be able to expel occupying armies. Someone said "what about the kids of Chinese people" and the sponsors said "yep, if we adopt this language they'll get to be citizens too".

None of it's complicated. You could read this as an 8th grader and have no doubt what they were trying to do.

Most of the discussion was of the form "hey, could we add an exception to exclude even more people from citizenship" and then the sponsors would say something like, "yes, we agree that those people aren't excluded under the current language; that adding extra language could exclude those people; and that we don't want to exclude those people or change the language." And then Congress voted for the language exactly as it was originally proposed.

matthewdgreen··on Supreme Court upholds broad conception of birthright citizenship
What are the confusing words? You gave a quote that sums up the long-accepted understanding of who's exempt from the citizenship clause:

"This will not, of course, include persons born in the United States who are foreigners, aliens, who belong to the families of embassadors or foreign ministers accredited to the government of the United States, but will include every other class of persons."

They don't mention Indian tribes in that quote, but they mention it elsewhere. Seems completely clear to me.

matthewdgreen··on Supreme Court upholds broad conception of birthright citizenship
There's nothing terribly confusing here. In fact it's a helpful set of quotes. This is one Senator saying "hey, second-generation Chinese immigrants will be citizens. And that's fine because I don't think there will be too many of them."
matthewdgreen··on Supreme Court upholds broad conception of birthright citizenship
The thread was about someone misunderstanding what "subject to the jurisdiction" meant. Someone suggested that it meant subject to US laws including conscription and income tax, another person said "what if the law in question doesn't mandate conscription of foreigners" and then Telemakhos gave a pretty confusing answer to that. At some point you dropped in to make a further confusing and argumentative comment in response to that, so I tried to clear it up. If you were just disagreeing with Telemakhos, then I apologize for misunderstanding.

I hope that's an accurate summary?

Here's part of the Senate debate where they discuss it. It turns out that they were extremely precise about what it meant, and they described the exceptions in great detail. It's even typewritten. The downside: you can't come away from reading this stuff and pretend like there's some legal flexibility in the term. If that's important to you, you probably shouldn't click the link.

We got wrecked in a major land war in the 1800s, just to be pedantic.

I don't have to imagine it. I live there. It's the richest and most powerful country on the planet. I hope you get a chance to live here someday!
matthewdgreen··on Supreme Court upholds broad conception of birthright citizenship
I think this take is overly complex and silly. If you're subject to the laws, that's that. As an exercise, go read the Federal code and put each law that might potentially be applicable to people on a work visa into a pile. I guarantee that pile will be taller than you are by the time you're done. It will certainly be larger than two random examples.

You're trying to impute complexity to a thing in order to achieve a goal that is not achievable. The 1866 Congress that debated the amendment understood and intended that Indian tribal nations would not be covered by the clause because they were separate nations not under the jurisdiction of US law. Here's an example of the debate [1] where they discuss it. Far from making your point, examples like this make it obvious that everyone involved in framing the amendment thought deeply about what "jurisdiction" meant, which is why you can't just assign new meaning like "yeah it means parents have to be citizens."

I really urge you to read the original debate. It isn't like the handwritten notes we get from the 1700s; it's typewritten and the Senators are so thoughtful and utterly precise about what they meant. It's ELI12.

The exception listed in Wong Kim Ark are: Indian tribes, children of diplomats, births on public foreign ships, and children of enemy occupiers. These were basically well-understood exceptions under common law and most were discussed during Congressional debate on the 14th.

Durable control of elections, and maybe one or two more justices.
matthewdgreen··on Supreme Court upholds broad conception of birthright citizenship
It's worse than that. The text of the statute is literally the same as the text of the 14th amendment's birthright clause. So he's basically saying the text means one thing when it's a statute, but the exact same words might allow exceptions in the context of the Constitution.
matthewdgreen··on The AI Industry as You Know It Died Today
The great thing is that many of the Chinese open-weight models can be run on US providers. Some promise not to retain data for training or other purposes. (Which I think is a credible promise most of the time.)
matthewdgreen··on Vulnerability reports are not special anymore
I think that’s an assumption. Just because an LLM might be able to find some bugs does not mean every attacker has a packaged attack, or the right prompting. The easiest way to find a vuln is just to Google for it.
matthewdgreen··on Vulnerability reports are not special anymore
Vulnerability reports are a voluntary service to help a vendor or software project. It’s often an annoyance for the security researcher. I understand people are getting slammed and it sucks, but the main result of rejecting them is going to be an increase in full disclosure. As a note: if you have a bug (that isn’t devastating but you’d like to talk about) having an LLM write up the disclosure is a great way to check the “we disclosed responsibly and they didn’t care” box.
matthewdgreen··on Reid Hoffman says SpaceX 'not an AI company', xAI 'complete train wreck'
The SpaceX S-1 says they’re going to be making $320bn by 2030 on AI services at a profit margin of 74%. That dwarfs all the launch business and even Starlink, which they very optimistically project as well. This is how they supported the IPO valuation.
matthewdgreen··on Curl will not accept vulnerability reports during July 2026
I'm thinking of something on the order of Heartbleed. Sure, you fix it in your own servers. Are you sure you're ok with the entire Internet being vulnerable for two months? You don't have any data stored on servers that are outside of your control?
matthewdgreen··on Curl will not accept vulnerability reports during July 2026
Doing the fix yourself is almost always the easy part. Disclosing it and getting a patch shipped across the entire Internet is the hard part.
