Maybe worth noting in the title this is from Cory Doctorow.

HN rarely (never?) attributes authors in the titles of articles.

Why should we make an exception in this case?


For me it would be a strong signal to skip the article and discussion, YMMV.

The engineering is not stellar either. 96% of the line's crossings are at grade. Those intersections are undersignaled with barriers that are easy to drive around.

If you know anything about Florida drivers you won't be surprised to hear there have been 180 fatalities on Brightline since its inception in 2017.


No doubt the public blames the trains rather than the drivers


> you won't be surprised to hear there have been 180 fatalities on Brightline since its inception in 2017.

... Wait, _seriously_? That seems implausibly high, for one not-very-frequent train line. Are these just uncontrolled crossings, with no barriers, or something?



Couldn’t read it on archive.org for some reason so I am adding this link for others in case they can’t either.

This is functionally equivalent to the Enabling Act of 1933. [0]

[0] - https://en.m.wikipedia.org/wiki/Enabling_Act_of_1933


Only eerily not legislated


Our legislature willingly gave up its power quite a while ago.


Incorrect, one party in the legislature gave up its power


Can you outline the argument as to how? It seems quite different according to the article. The courts still assert supremacy when it comes to interpreting and vetting the law, and Trump isn't allowed to overrule the legislature's lawmaking powers.


It creates imbalance of power: the executive can keep making orders which are clearly unlawful, but because of this they are still gonna be applied to most of the people (apart from ones who can afford going to court) until SC will reach the orders on merits meaning not soon. Meaning by that time executive can make new orders.

I think you’ll see this playing out very soon.


Also it is not a constitutional change.


The "Enabling Act" described in the linked article allowed Hitler to legislate unilaterally. This decision concerns judicial review of executive orders, and every presidential executive order is still only valid if it derives its authority from a valid act of Congress, a treaty entered into, or a self-executing provision of the Constitution itself.


Any AI will most certainly reflect the biases of the bureaucracies responsible for their creation.


Nah AI can easily be programmed to be much more patient and investigate edge cases and figure out personalized solutions thoroughly and provide bespoke service. This problem would be solved, though of course there are other issues with biases of the bureaucracies.


If you can do that easily, you will have no shortage of investors. But it’s not easy - getting the data alone is a huge problem.


I think OpenAI has plenty of investors...

OpenAI doesn't lack investment capital. What they still don't have is a good source of high quality clinical data. And this isn't just a matter of buying access to deidentified patient charts from some large health system. Most clinical data quality is kind of crap so using it directly for model training produces garbage output. You need an extensive cleansing and normalization pipeline designed by human clinicians who understand the data at a deep level.


Absolutely true, but is there a system that works perfectly that I can use now that has all that that isn't AI?

In the absence of such a thing OpenAI is already quite good, some theoretical perfect shouldn't be trotted out as a counter if it doesn't actually exist.


There is a massive difference between being able to discuss symptoms and actually being diagnosed. Diagnosing edge cases is precisely the kind of thing that a generative AI needs massive amounts of data on. Where is this magical data source that violates doctor patient confidentiality? And all the doctors just contribute to it and everything is fine? Come on…


That’s true but they have a massive shortage of clinical data. Doctor patient confidentiality is a thing.


Assuming the neighbor to the north gave up air rights, could this be corrected with guy wires planted in the park one block away?

Makes me think a kerbal citybuilder game would be fun.


The article makes it sound like there is nothing to correct. The structure is crooked, but sound.

You can build a house around it.


Yes, in the article it says many structural engineers over the years have deemed it “unlikely” to have major issues.


Consider watching Paul Shraeder's _First Reformed_.

We're all nearly powerless but our choices do matter.


My experience is that cars manufactured in the past 10 years can withstand salty rust belt winters with little or no corrosion. I'm sure metallurgy varies between manufacturers but I think you're underestimating how much practices have improved.


This is correct.

On the automotive scale, rust is a solved issue.

Nickle dip, electro deposition coatings, powder coating, salt spray testing, limited exposed welds.

GP is incorrect. Rust is not the issue for avoiding steel.

It is weight. Period. Every group at every mfg is given a weight reduction goal per model line and refresh. Vehicle network systems had a bullet point not of safer, or easier, or redundant, which it is none of those things - but low weight as you can cut a lot of copper out.


Some of the site's infrastructure is using an expired cert referencing letsencrypt R3 and other bits are serving a working cert at letsencrypt R10. Broken ACME updates maybe.

This can be so hard to get right! But I guess an automation oopsie is a step up from the need for spreadsheets, NMS checks, calendar reminders, and still having things expire once turnover erodes institutional knowledge.


I appreciate an abstract that doesn't beat about the bush:

The collapse time is estimated between 2037-2064 (10-90% CI) with a mean of 2050 and the probability of an AMOC collapse before the year 2050 is estimated to be 59 +/- 17%.

We'll miss you, Gulf Stream.


The AMOC and the Gulf Stream are two separate systems.


For those curious, I found this article[0] going into the details, differences, and interactions between them.

TLDR: the Gulf Stream originates from a very different phenomenon than the AMOC and is not at risk of collapse. A small part of the heat transported by the Gulf Stream does originate from the AMOC though, but its collapse would be much less severe than a full collapse of the Gulf Stream.

The Gulf Stream is part of the AMOC.


Wonder how much immigration this will create from northern Europe. AIUI the collapse will make those countries quite chilly.


I wonder how the summers would be under this scenario. Cold winters alone wouldn't be such a huge problem, but if food production collapses then we'll be in trouble.


I think both would be an issue. Most of Europe is pretty far north with the equivalent latitudes in Canada not having much agriculture or people living there frankly. Edinburgh is just slightly south of Juneau so I think any growing season would end up being too short for most crops.


We really, really will.
