Excited to announce that my work on Bleeding Out w/ @LaurenCaruba got third in the Phil Meyer Award!
As someone who learned about Meyer on my first day of data journalism class at UNC, this is a huge honor for me.
Replying to @IRE_NICAR
Congratulations to @dallasnews and @ExpressNews for earning the third place prize. “Bleeding Out” investigates why tens of thousands of injured Americans die from preventable bleeding each year. interactives.dallasnews.com/…

News: I'm told there was a very combative meeting of the CBS News London bureau today held by foreign editor Shayndi Raice.
Raice, I am told, "lectured" staffers about hierarchy, obedience and management’s right to dictate editorial decisions, explicitly warning that ignoring instructions could constitute insubordination and grounds for dismissal.
I am told that CBS News senior foreign correspondent Holly Williams pushed back on Raice regarding an incident mentioned in last night's edition of Status -- about an Evening News report on the anniversary of the Oct. 7 Hamas attack that omitted the death toll from the war in Gaza .... and Raice defended the decision.
Lesley Stahl’s 60 Minutes report on extremist Israeli settlers underwent a contentious screening process at the Bari Weiss-led CBS News, leading the veteran correspondent to privately express the possibility of quitting the show

Dusting off this tweet from April because this gap in shared understanding of LLM capability is *widening*. It's now less "two groups of people speaking past each other" and more a sharp funnel.
- Napkin math somewhere around 6B people (~75% of the population) have barely come in contact with LLMs at all.
- Around 1-2B (~20%) are casual and infrequent users of free-tier ChatGPT-like products. This group sees derpy chatbots and treats them a bit like a better Google search, a writing aid, or etc. Maybe an agent tries to book you a flight. I have non-tech friends who (reasonably, imo) say they have not much use for it at all. Even many professionals outside of math&code are in this tier. For example, execs and many other functions spend a lot of their time talking to other people, so while they understand what is happening intellectually, it is still second-hand and a bit abstract.
- Now we get to professional use of frontier-grade LLMs in math&code. Somewhere around 20M people (0.2%) see first-hand that large, complex projects that used to take them weeks/months can now be completed by agents with a prompt. Building apps, copying apps, translating apps, decompiling apps from binaries... This has all happened very quickly and recently - less than 1 year ago, I was writing code manually by hand, typing memorized computer code commands into a code editor character by character, occasionally pressing Tab to autocomplete a little chunk of code.
- And finally we get to the ~5,000 people (~0.00006%) with access to frontier-grade systems internally. The external world has seen the preview. It looks like swarms of thousands of agents collaborating over weeks on software mega projects: minting zero days, running cyber attacks and defenses at machine speeds, discovering new science, advancing the frontier of mathematics. Things that would have taken top professionals in the industry years of work. Meanwhile, human review and comprehension are starting to fall behind. For example, people are still involved in the "archeology" of the OpenAI-HF incident from many months ago. Mathematicians may be poring over the 722 manuscripts on frontier mathematics for a while.
The funnel is driven by a combination of factors:
1. The impact scales with ambition, problem size, and horizon. A question with a paragraph answer barely stresses the system. You need a reservoir of big, difficult problems that you really care about. This aspect drives the consumer / professional dimension of the funnel.
2. The jaggedness of the system (which I have written about a lot separately). Capability peaks in domains that are digital, verifiable and economically valuable. This is because LLM capability emerges from reinforcement learning on verifiable rewards on a curated environment mixture driven by revenue potential. This aspect primarily drives the area (e.g. math&code) dimension of the funnel.
3. Access. Free-tier, paid-tier, internal.
So this is the weirdness of the moment. The general public has mostly not interacted with these systems. When they have, it looks like a derpy chatbot. The majority of professionals still see only a modest uplift. And a small sliver of professionals are experiencing the vertigo of the curve going vertical. And it is all happening at the same time.
Judging by my tl there is a growing gap in understanding of AI capability.
The first issue I think is around recency and tier of use. I think a lot of people tried the free tier of ChatGPT somewhere last year and allowed it to inform their views on AI a little too much. This is a group of reactions laughing at various quirks of the models, hallucinations, etc. Yes I also saw the viral videos of OpenAI's Advanced Voice mode fumbling simple queries like "should I drive or walk to the carwash". The thing is that these free and old/deprecated models don't reflect the capability in the latest round of state of the art agentic models of this year, especially OpenAI Codex and Claude Code.
But that brings me to the second issue. Even if people paid $200/month to use the state of the art models, a lot of the capabilities are relatively "peaky" in highly technical areas. Typical queries around search, writing, advice, etc. are *not* the domain that has made the most noticeable and dramatic strides in capability. Partly, this is due to the technical details of reinforcement learning and its use of verifiable rewards. But partly, it's also because these use cases are not sufficiently prioritized by the companies in their hillclimbing because they don't lead to as much $$$ value. The goldmines are elsewhere, and the focus comes along.
So that brings me to the second group of people, who *both* 1) pay for and use the state of the art frontier agentic models (OpenAI Codex / Claude Code) and 2) do so professionally in technical domains like programming, math and research. This group of people is subject to the highest amount of "AI Psychosis" because the recent improvements in these domains as of this year have been nothing short of staggering. When you hand a computer terminal to one of these models, you can now watch them melt programming problems that you'd normally expect to take days/weeks of work. It's this second group of people that assigns a much greater gravity to the capabilities, their slope, and various cyber-related repercussions.
TLDR the people in these two groups are speaking past each other. It really is simultaneously the case that OpenAI's free and I think slightly orphaned (?) "Advanced Voice Mode" will fumble the dumbest questions in your Instagram's reels and *at the same time*, OpenAI's highest-tier and paid Codex model will go off for 1 hour to coherently restructure an entire code base, or find and exploit vulnerabilities in computer systems. This part really works and has made dramatic strides because 2 properties: 1) these domains offer explicit reward functions that are verifiable meaning they are easily amenable to reinforcement learning training (e.g. unit tests passed yes or no, in contrast to writing, which is much harder to explicitly judge), but also 2) they are a lot more valuable in b2b settings, meaning that the biggest fraction of the team is focused on improving them. So here we are.

Imagine you are leading the @IRONMANtri World Champs after taking the win last year and you completely shut down 1km from the finish line..
Utterly insane from Lovseth AND somehow she still managed to finish the race.
Ironman triathlon is BRUTAL.

The Ironman World Championship is sport’s most brutal race.
It features a 2.4-mile swim, 112-mile bike ride and 26-mile run - all in searing Hawaii heat.
Last year, Solveig Lovseth won it.
These are the secrets to being the world’s fittest woman, featuring three-hour sleeps, post-race burgers and being her own ‘cheerleader’.

The pitch meetings at propublica must be wild.
📸 Check out the handwritten application we submitted to found a private school in West Virginia.
We were approved as a microschool. A state spokesperson said it “does not approve or deny the operation of microschools for any reason.”

I have two journalism degrees, including a graduate degree (not from Columbia). Here's my thoughts on the Journalism Grad School Discourse:
Journalism is strange in that we have no formal standards like law or medicine but we do have strong norms. These degrees can be also be used as an inappropriate proxy for understanding/agreeing with these norms.
Many of my Berkeley classmates did not agree with them at all.
NYT editor @dylfreed says AI is great at code for the exact reason it’s mediocre at writing:
"If you give an AI a prompt 1,000 times that's roughly similar, the outputs are gonna be roughly similar, whereas humans would be way different."
"You can fine-tune it to be really good at writing in a very specific way, but it's always gonna be mirroring that way. Getting that diversity is still a challenge for LLMs."
"With coding tasks, it's like, 'I don't wanna be super original. Just give me the thing that a million people have built and tweak it slightly, and I'm happy.'"
