djoldman··on A map of 5000+ midterm ads
> If nobody votes, what happens?

This is like asking, "if pigs could fly, what happens?" -> all sorts of things... but pigs can't fly.

"if nobody votes..." is a hypothetical that has never been true because people DO vote. I don't know of a good reason to believe they'll stop voting. Obviously the futility of voting to change the election outcome isn't stopping them so far.

djoldman··on A map of 5000+ midterm ads
Looking at history, one person choosing to vote is statistically useless if the goal is to influence the outcome of a presidential or congressional/senatorial election in the USA.

The chance of one vote being the difference between a tie and a win for a candidate has been approximately zero. And in the extremely rare times when there has been such a one vote difference, there have been re-counts that conclude with a margin that is larger than one vote [0][1].

Mathematically/statistically this makes intuitive sense. One might ask: what's the chance that a vote ends in a tie when there are 10, 100, 100,000... 10 million voters? As the voting pool increases, the chance decreases.

The most common objection is along the lines of, "if everyone decided not to vote because their vote didn't matter, then no one would vote!" Yep, that's correct... but that doesn't describe reality: clearly people vote a lot.

Voting because one enjoys it, gets satisfaction of some sort from it, feels that they are doing their "civic duty" and discharging a responsibility, etc... that's fine. But don't vote because you think you're gonna change the outcome.

djoldman··on Google will turn off search for schools that reject AI
As usual, the truth is a little less clickbaity. It's just opt-in:

https://blog.google/products-and-platforms/products/educatio...

> We believe schools should have control over AI in their classrooms and in providing administrators with controls to help them manage their approach. After listening to schools, teachers, leading researchers, and policymakers, we are now updating our approach to controls for Gemini, Gemini Notebook, Gemini in Classroom, and Google Search. Access to these products will be entirely off for K-12 student accounts until school administrators explicitly turn them on.

djoldman··on Mathematics has changed. Let's act like it
If they did that and were able to find someone to pay them, that'd be a pretty good contribution, no?
djoldman··on Everyone Has Email. Nobody Uses It Right
> You can't DM famous people on Instagram and expect a response, but send them a thoughtful email and suddenly you're having a conversation.

Easy to find email addresses of famous people are unlikely to respond to you to say the least.

djoldman··on Copyright Office is restoring copyright to something you have to work to get
> The simplest, most reliable way to ensure the works you invest in are fully and entirely eligible for copyright is to just use humans for the whole project. Declare a "no-AI policy," and hire human artists to produce the works you hope to sell. Monitor their activity to ensure they're not using AI. Keep good records.

That seems true.

But also: generate all you like and then have humans edit, and keep a record of it, seems plausibly defensible too.

The current state of a lot of AI generated content material, not all / not necessarily program code, seems to really benefit from human editing.

djoldman··on Ousted Savannah police officer gave ICE agent husband access to Flock system
It's almost never like that. Usually some team collaborates with some other team and sets something up with approval from departments A, B, and C with director X signing off. There's rarely one person you can point to. Also, wait a year and all those As, Bs, Cs, and Xs have switched to different roles or don't exist.
djoldman··on How employment is changing at Anthropic
> Even if the overall productivity boost due to AI "only" turns out to be 40%, the lowest among your numbers, it's equivalent to 17 years of growth at 2% per year.

Two reasons to question the 40% number:

  - Anthropic probably represents the extreme case of AI adoption, if they're not the absolute leader. I would see 40% as the absolute max for that category without knowing anything else.
  - Anthropic is a tech company, willing to change their workflows rapidly, having maximal enthusiasm for the technology, and maximum knowledge of it. The vast majority of the world's companies don't come close to it for these aspects and therefore adoption and speed should lag significantly compared to Anthropic.

djoldman··on Will it be a golden age or a dark age for mathematics (and science)?
> For those hard theorems where we really want LLMs to help us, these Lean proofs are extremely long, like hundreds of thousands of lines of code long. A seemingly emergent trend is that the longer the Lean version of a proof, the messier and less faithful its machine-generated “natural language” translation seems to be.

This seems to be a common and continuing objection to the OpenAI math repo release. Specifically that at least some, perhaps many of

  * the natural language proofs are low quality or otherwise extremely difficult to understand (although possibly correct?)
  * the lean proofs are too long, convoluted, or otherwise extremely difficult to understand
I wonder if LLMs will be able to generate "high quality" natural language and lean proofs soon.

And specifically: iterate on the OpenAI repo to produce "better" proofs that prove the same things.

djoldman··on How employment is changing at Anthropic

  Commits per engineer 5.1x
  Queries per data scientist 3.1×
  Contracts per legal employee 3.1x
  Deals per salesperson 1.7x
  Hires per recruiter 1.4x
  Invoices per AP processor 1.4x
These are the stats that might be hiding the possibly small potential for AI to generate "real" economic activity.

The first 3 stats, commits+queries+contracts, are secondary/meta statistics that could possibly go up 1000x and have very little affect on Anthropic's business, whereas that's much less likely to be the case with the last 3.

AI can make it very easy to do more and more busywork that doesn't move the needle.

If the above is true, AI econ must rely on a second order effect here in that busywork/BS is recognized more quickly and discontinued.

For example, if an organization paid an employee to compile a monthly report and it took them a very long time. But with AI, they can make that report every day. Now the organization realizes that they don't even need it.

djoldman··on How employment is changing at Anthropic
> Anthropic has expanded rapidly. But it has hired less per dollar of revenue than an earlier generation of large tech companies. At five years old, Anthropic takes in between 2–4 times as much revenue per employee as Meta and Google as they crested in their own rapid growth.

This may not be saying much at all. So much goes into deciding how fast to hire. Instagram had 13 employees / 1B rev at acquisition?

Also revenue per employee can vary a lot depending on the industry.

A better metric to understand AI effects might be revenue per employee at companies that have been around > 5 years that are AI-enthusiastic.

djoldman··on Show HN: Gemini 4 Argon plays StarCraft
> ... runs each model in its lab's 1st party CLI harness at the highest reasoning setting it offers.

  Anthropic (Claude models): Claude Code
  OpenAI (GPT models): Codex
  Google (Gemini models): Antigravity CLI
  Meta (Muse models): Muse Code
> The CLIs' web search and web fetch tools are turned off, and the agent has no other internet access. The CLI is installed before the clock starts, and the hour counts from when the agent starts. There is no submit tool: the harness collects the bot when the time runs out.

One thing we're learning is that harness is HUGE. The difference in performance for the same underlying model can change dramatically across:

1. harnesses

2. allowed tools (no web search/fetch - how does the model refer to documentation?)

3. thinking levels

Thank you!
djoldman··on There's little that's "inevitable" about AI
> The technology can, in volume of adequate output or in quality of output, overwhelmingly outclass what alternative technologies can do. A moderate improvement isn't really enough to force inevitability: it has to be a massive difference.

> Now we come to the question of whether or not the difference that LLMs bring to the table is sufficiently overwhelming to make their adoption inevitable, and on this I think the answer is a clear no. As established above, LLMs just can't do top-flight work at all: at the heights of basically any discipline, we're still very much relying on unaugmented human work.

The clear flaw here is that cost isn't taken into account. A new technology needs to be better than the status quo at a given cost/price point.

Examples: mass produced textiles, photography, IKEA. Ostensibly not the highest quality, but the cheapest at a price point.

djoldman··on 100+ reactions to 100+ solutions
Please explain 2 things:

1. "...these open problems were curated in order to organize a field around, most to all of them only have/had value in so far as they promoted study of the subject" - I don't understand, how were the open problems curated? Do you mean that mathematicians put a lot of work into coming up with the problems and now all that work is somehow worthless now?

2. "OpenAI is functionally reducing the communities ability to ask real questions." How? Let's assume all the remaining proofs are correct (big assumption): how does resolving conjectures reduce the ability to pose new problems? This only makes sense to me if the assumption is that there are a relatively small number of possible problems to solve and so it's like a game that's coming to an end with no more interesting areas to explore. Surely math is bigger than these?

djoldman··on 100+ reactions to 100+ solutions
An interesting split in reactions by people who work in mathematics to the OpenAI release:

1. Reacting from the POV of the individual person: disappointment, disillusionment, and/or grief from those who've worked on some problem for years and now don't have something to work on; it's been a part of their identity. As well as those whose career tracks and plans were thrown in disarray.

I wholeheartedly sympathize with the above.

2. Reacting from the POV of the entirety of mathematics as a field of study/research:

  "If OpenAI wanted to destroy the mathematical community, this would be a great way to go about it."

  "...it will create conflict in the mathematical community;"

  "I feel that solving so many problems in such a short time may damage the math community and profession"

  "They can simply release multiple 100+ page papers claiming to have solved this or that problem, often with redundant arguments, ... — in other words, slop. And we are then expected to go through it, check it, clean it up, simplify it, and explain what is actually going on. This comes at a considerable cost to us ...And, of course, the credit remains theirs."
This second type of reaction... is confusing. No one is forced to read any of the papers. Ignore them if you want. But also, isn't reading papers a lot of the job?

  "Open problems are a resource that the mathematical community developed over decades or even centuries"
I doubt mathematicians have intentionally not solved problems just so that they can remain unsolved? Build on these advancements (or disprove them - wouldn't that be an amazing result!) and pose new problems?

What if a human dropped all of these without AI? I suspect there wouldn't be the same reaction for some reason.

djoldman··on OpenAI, the Partition Principle, and Mathematics
The response by some in the field of mathematics to this repo is ... I guess not unexpected; but it's quite disappointing.

I sympathize with those who've worked on some problem for years and now don't have something to work on; it's been a part of their identity. I also especially sympathize with those whose career tracks and plans were thrown in disarray.

That being said, I absolutely cannot understand how one can't be excited and happy and enthused about these advances in one's field. Assuming just that the ones with formal lean proofs are actually true, these are reportedly huge advances. Even if folks don't understand it YET.

djoldman··on Subquadratic 3SUM and Subcubic APSP
> Claude, an AI model developed by Anthropic, discovered the algorithm that refutes the 3SUM, APSP, and Exact Triangle hypotheses. The authors then worked to understand, simplify, strengthen, and extend the algorithm, derive additional consequences, and make the presentation accessible. See “Acknowledgments and Methodology” for how the result was found and shared with the authors. The authors take full responsibility for this paper.

> Claude also verified this paper’s main results using the Lean 4 proof assistant with the Mathlib library.

djoldman··on Oracle Triggered the Implosion of the AI Bubble
The bigger story in all of this is the follow on to the answer to: "how do they plan to pay for it?"

They plan to pay for most of it through excess cash flow, aka profits.

Follow on question: "they make $100s of billions per year? what did they do with all that previously?"

Answer: share buybacks, nothing (aka put it in the bank), acquisitions.

These companies make a ton of money and have a ton of margin over expenses.
