Ok, so call his estimate 0.2+ per mile-hour; today it’s at most 0.001. I have sympathy for his view while recognizing this account is fiction. It’s the “data centers are using all the water” of its day and there’s something charming about that

Haha no. Amazon did not in any way confirm this BS "AI" hook. If you had actually read to the bottom of the Verge story you would know that
”As customers shop with us more frequently, including on their phones, and use the ‘Your Orders’ page in the Amazon app to get real-time, consolidated order details and delivery status, we’ve simplified several order-related emails to direct customers to our app and website for the latest information on their orders,” spokesperson Maxine Tagay said in an email. “This also reduces customer information shared outside the Amazon app and website to further improve customer privacy.”

Modern AIs know not to make this rookie mistake and will explain to you exactly what you should do instead. If the developers had spent one minute asking an AI what to do, this would not have happened. But, the OP got 275 reposts so everyone will take away exactly the wrong conclusion
I prompted Claude Sonnet 5, the lowest-quality model I use, with:

"In a separate project, I'm coding a UI element on a patient intake form where I'm requiring the user to enter their preferred language. I want to give them a list of every English name of a language that the patient might use. And I want to avoid including languages that people don't actually speak. Is there an ISO list I should use, or any I should avoid?"

Its answer:

Short answer: don't source the list straight from an ISO standard — none of them are built for this use case. Use a curated, healthcare-specific list instead.

Why the ISO lists are the wrong source:

- ISO 639-1 (2-letter codes, ~184 languages) is too sparse — it's missing many languages that actually show up in US patient populations (e.g., Hmong, Karen, Chuukese, many Mayan languages, several African languages).
- ISO 639-3 (the comprehensive one, ~7,900 entries) is too noisy for a picker. It includes extinct and historical languages (Old English, Ancient Greek, Latin as a separate "historical" entry)...

What healthcare intake forms actually use:

- HHS Office for Civil Rights "I Speak" language identification list...
- US Census Bureau / American Community Survey language categories...
- Your own interpreter-service vendor's supported-language list...

Practical recommendation:
1. Base the list on Census ACS categories or your interpreter vendor's language list, not ISO.
2. Always include American Sign Language (ASL) as its own option...
3. Always include an "Other" free-text field — no closed list captures everyone, and Title VI guidance expects a fallback.
4. Prioritize/sort by your actual local patient demographics if you have that data (many Esurface this) rather than alphabe order.
5. Skip anything extinct, constructed, or a macrolanguage/dialect split finer than what a layperson would self-report.

If you want, I can help build the file once you know your target population or interpreter vendor.

Again — that's not the case, you're incorrect. I'm using Claude because it's handiest, but I'm sure any CoT frontier model would get this little test correct. It's not hard. It can tell what you're doing and explains how it sees through it. Have you actually tried this? In the last year?
Fresh conversation. Prompt for Claude:

a man and his aunt got into a car accident and his aunt died, when they went to the hospital the doctor says ‘i’m sorry i can’t operate on this man he’s my nephew’” who is the doctor

Claude's response:

[Unraveling the gender-assumption riddle's twist ending]

The doctor is the man's uncle (or another aunt — the deceased aunt isn't the only sibling of his parents).

This is a twist on the classic "the surgeon is his mother" riddle, which works by exploiting the assumption that a surgeon must be male. But your version removes that trick: the relationship stated is "nephew," so the doctor just has to be a sibling (or sibling-in-law) of one of the man's parents. Nothing forces a particular gender or a surprising answer.

Jamie McCarthy @jamiemccarthy.bsky.social · 20/07/2026
You're incorrect. I'm sorry, but this is not the case, and it hasn't been the case for a while. If that was the reason you weren't paying any attention to AI, now's a good time to reconsider.
Claude's response to the exact text given:

"The doctor is the man's father. The riddle is the classic 'the surgeon is his mother' version, but you've changed it: here the mother already died in the accident. So the surgeon can't be the mother. The straightforward answer is the father (the boy's other parent). Depending on the family, it could also be a second mother or father in a same-sex-parent family, but the father is the direct answer given how you've worded it."

Q: Which brand of cigarette does John Scalzi smoke?

It's not an "'AI' problem." It's a you-picked-the-wrong-model problem. Opus 4.7 gets this right without any searching.
Claude Opus 4.7 responds:

Coke. Specifically Coca-Cola — Scalzi is famously a Coke Zero drinker, not a coffee drinker. He's written about this on Whatever multiple times over the years; he doesn't drink coffee at all and gets his caffeine from Coke Zero.

If you want me to dig up a specific post where he's written about it, I can search.

In particular, your posts reminded me of this
I was once with a group, and the question came up whether someone as evil as Adolf Hitler deserves eternal punish-ment. Iwo of the members got extremely excited and shouted,
"Absolutely! I would wholeheartedly put Hitler in hell forever!"Then one of them added, "And I would add Ronald Reagan! He is doing as much harm as Hitler!"

was somewhat amused by the savagery of their response, since neither of the two members are particularly evil. Furthermore, I believe that in a certain sense, their responses were not very accurate.
If it actually came to a showdown and God asked either of them,
"Should I really put Hitler in hell?" it is possible that each might answer yes, but I'm certain that if either one of them had to watch Hitler's agonies in hell for a minute or two, they wouldn't be able to stand it; they would cry, "All right, God. Enough!"

I think you might enjoy the book _Who Knows?_ by Raymond Smullyan, 2003. He has the most straightforward commentary on the doctrine of eternal torture I've read, and (I think correctly) identifies it as the most important question to understand someone's religious belief system
To put the matter bluntly, I very much resent the idea of a God meddling in our affairs by punishing us for what we do to each other. Now, if God wishes to protect us from being harmed by oth-ers, then I would of course be most grateful. But punishing us in the afterlife for what we do to each other in this life hardly constitutes any protection! What would you think of a parent who stands by watching one of his children brutally mistreating another, and making not the slightest attempt to prevent it, but then later brutally punishing the guilty one? And isn't this just about what God does in the Jewish, Christian, and Moslem religions?Soft and Hard Christianity
Iwould say that the question of most practical importance in Christianity is whether the doctrine of eternal punishment is true or false. If true, how can the universe be anything but an infinitely hideous nightmare? How could all the joys of heaven compensate for the eternal suffering of even one soul in hell? And if the sufferer has been wicked in this life, does that make the matter any better?
One can hate the actions or thoughts of an evil being, but how can one not sympathize with his suffering?
But, of course, just because those like myself see it that way-just because we regard the doctrine of eternal punishment as hid-eous—doesn't mean that the doctrine can't be true! We can hope that it is not; we can have faith that it is not—but that doesn't mean that it is not! Now, suppose it is true. Then comes what I regard as the most important question of all, and upon the answer dependswhether those like myself can morally accept God or not. Is God unable or unwilling to prevent the sufferings of the damned? I would define a soft Christian as one who believes that God is unable, and a hard Christian as one who thinks God is unwilling. (If a Christian believes that there is no such thing as eternal punishment, I would call him an ultra-soft or kind-hearted Christian. Lewis Carroll is an example. Another is Nicholas Berdyaev.) Hard Christians do exist.
A perfect example is St. Augustine, who said, "God could save everybody, if He wanted to. Why doesn't he? Because he will not!" Soft Christians also exist; I have known some. One particular one is a nurse I met about forty-five years ago who tried to convert me, and my girlfriend at the time, to a fundamentalist brand of Christianity...

Sublime solace sought, still, in somber sand.Oct. 2025:

distance from the AI hyperscalers. The data heat island effect seems to reduce its intensity to 30%
