@fchollet The graph isn't quite a random walk; you've effectively added momentum to it ("persistence"). That probably models stock movements a little bit better, but it's not a pure random walk.

Ok, this thread has apparently been a magnet for hordes drooling morons who not only don't get stats, but can't even read. If you're a normally intelligent reader of this tweet, here's an extra example of my point: If you take two RANDOM, INDEPENDENT timeseries (i.e. knowing one gives you NO information about the other) that are each highly temporally autocorrelated (e.g. two random walks), and you plot one against the other as a scatter plot, what you get is a single X/Y trajectory that will ALWAYS look very structured. Yet it is random. Like the figure below. Code to reproduce the figure and play around with this idea: #scrollTo=MACHekU7eirD" target="_blank" rel="nofollow noopener">colab.research.google.com/drive/1FIk8j_A… Of course if the two series happen to be correlated, then you will ALSO see something very structured. It's just that this type of visualization is a completely retarded way to look at such data. If you think this is deep, you are innumerate.

This is a type of chart crime: when you plot value tuples from a timeseries on a 2D scatter plot like this as if they were independent samples, you are leveraging temporal autocorrelation to magnify any existing x/y correlation and hide the actual variance. You're also hiding temporal distribution drift (the typical value range for x and y, and the relation between them, change over long periods)

One part of the heroics discourse is “Employers do not successfully reward heroics and therefore expectation for them is breach of the implicit contract”, about which I feel “… It depends. How familiar are you with tech compensation structure.”

@patio11 Heroics suppresses a pain signal that an organization needs in order to adapt. It can be different if heroics are being applied to maintain a steady state, but heroics can inhibit adaptation when things are ramping up.

@mentalgeorge Society would fall apart if people were not mostly moral. This isn't an either/or situation. You need both: hard rules to guard against deviance and set a perimeter on permissible action, and fundamentally moral action so that rules don't need to be harshly illiberal.

I'm also partial to old-school liberal critiques of the Claudian approach. Empowering an agent to act on the basis of its own reasoning rather than the letter of the law is dangerous business. This is precisely the view that, in Isaiah Berlin's words, empowers one "to ignore the actual wishes of men or societies, to bully, oppress, torture them in the name, and on behalf, of their 'real' selves."

More on OAI's model spec. This time, I'll cover the section that most distinguishes OAI's liberalism from Anthropic's Claude-as-philosopher-king approach. #2 - "No other objectives" Almost infinite material for discussion here

@0xluffy It's ironic that they talk about releasing it early for cyber defense, and yet the leak seems to be down to poor cyber defense practices.

so Anthropic been training a new model “Claude Mythos” and claimed to be “by far the most powerful AI model” they’ve ever developed - CMS error exposed 3,000 unpublished internal assets - blames human error in CMS for the leak - new tier Capybara 🤨 larger than Opus - scores higher on software, academic reasoning, cybersecurity - claims that model is far ahead of any other AI models in cyber capabilities, can exploit vulnerabilities that outpace defenders - cue “too dangerous to release” again Anthropic is afraid of releasing a model they built themselves. but OAI said the same thing before i wonder

JUST IN - Leaked documents from Anthropic show that a new generation of super-strong models, "Claude Mythos," is already in testing with Anthropic believing it "poses unprecedented cybersecurity risks." — Fortune

@full_kelly_ @eliebakouch It's not token efficiency, it's move efficiency, to guard against brute force strategies. Models can generate as many tokens as they like.

@VictorTaelin API prices have huge margin. The plans almost certainly don't subsidize anyone except the heaviest users; most people won't max out their quota day in day on a weekly basis.

(also opus 4.6 fast isn't "15x more expensive" than normal mode (2.5x speed * 6x price) - it is actually more like ~200x more expensive, if you consider how heavily subsided the claude pro plan is right now...)

@paulnovosad @Scholars_Stage It's more than that. The more ICE is reviled by the people, the more ICE members need to side with their masters and obey them, to save their own hides.

@Scholars_Stage Isn’t it obviously because the chaos and escalation is exactly what some people in the administration want to see? Every bit of violence gets us closer to a Reichstag fire.

Here is what I don’t understand. I saw probably 50 people make this point between November 2024 and January 2025, including some people who went in. So why did it not happen? I assumed they discovered legal hurdles that made it difficult—was my assumption wrong?
Christopher F. Rufo ⚔️@christopherrufo

We talked about this on the podcast: You can’t scale ICE raids. Eventually, you have tighten the screws on employers, create banking restrictions, and tax remittances at a high rate, all of which will incentivize self-deportation—the only path for significant change.

@Scholars_Stage You're mistaking the goal and the means. The goal isn't deporting immigrants. The means - an army of violent thugs - is the goal: having what effectively amounts to a domestic army with blood on its hands, so that it needs to side with the authoritarians, and not with the people.

@Miyhnea It can go the other way. It can be that incumbents in a more functioning country can leverage their weight to suppress competition and protect monopolistic rents.

One Tuesday night, as my wife and I sat down for dinner, a sheriff’s deputy knocked on the door to serve me a subpoena from OpenAI. I held back on talking about it because I didn't want to distract from SB 53, but Newsom just signed the bill so... here's what happened: 🧵

@rickasaurus I'm not sure. Broad shallow software is at risk; stuff you go to do a one-off or simple task. You can craft it quickly. But software that is deep, that multiplies in value with each feature addition, isn't going away, especially if the data isn't easily transported.

If you’re wondering it’s kind of reminiscent of fig jam. It’s a really nice flavor along side ice cream or pastry.

NEW: Progressives have a birth rate problem For all the talk of a general fall in births, the drop is overwhelmingly driven by people on the left having fewer kids. By ceding the topic of family and children to the right, progressives risk ushering in a more conservative world.
