Terry Tao talks about how he used to try to cooperate with the AI industry to achieve a positive outcome, but now he finally sees their true colors. Link

During this event, OpenAI requested an interview concerning my vision of the future of AI and mathematics. I accepted, and spoke with them for perhaps an hour. I had done similar interviews in various venues, and I assumed that, as with these other cases, they would eventually post the entire interview online, which talked about both the possibilities and risks of AI much as I have done in these other interviews. As it turned out, they only used a few snippets of that interview for that infamous advertisement instead. In retrospect, I should have pushed back harder on their decision; but I decided at the time that even a selective release of my commentary would help raise awareness of the potential for AI, and in particular on the possibility of the “best of both worlds”.

Since then, the situation has deterioriated markedly. Many of the people in the industry that shared my views have left or become sidelined, with most major tech companies now increasingly focused on the race to develop extremely powerful, autonomous AI technologies regardless of their actual value to society. The current drama surrounding the Navier-Stokes global regularity problem is the most dramatic and visible instance of this, but there have been multiple other such examples, and much of my commentary in the last few months has been aimed that the increasingly severe divergence between the current objectives of the AI industry, and of mathematics in general.

Much respect to artists for seeing all this coming from the very beginning, and holding the line.

One detail that seems to have not spread around: the announcement was so rushed that when the 165 page output was released, it only included 16 citations, and those citations did not even include the work of Diego Córdoba and Luis Martínez-Zoroa, who introduced the overarching framework for attacking the problem (that Buckmaster-Alpöge and OpenAI used). After the announcement and after these redditors pointed it out, they threw in a few more citations to include them, but come on.

Of course there are people trying to find a silver lining to this by conjuring up the hypothetical scenario where a student only uses the AI to aid in learning the material instead of just doing all the work.

First, any convenience in learning the material just reduces your ability to learn it. The friction involved with learning may seem like an inconvenience to be smoothed away, but it turns out that the friction is how learning happens. It's called engaging with the material. This has been the case with previous technologies: handwriting is better for retaining memory than typing (https://pmc.ncbi.nlm.nih.gov/articles/PMC11943480/), although it seems like AI is on an entire new level. (I guess there is some commentary about the sadly common worldview that life is about avoiding inconveniences. I feel like this mindset draws a lot of people to AI.)

Second, there is a very thin line between "helping" you learn the material and just doing the work for you. The temptation to cut corners is always there, and when you have the Corner Cutting Machine at your disposal, you are kidding yourself if you think you will have perfect discipline. Tools influence behavior.

Glad to see that OpenAI has not changed in their scummy ways. Despite all that has changed in the meantime, they have kept their time-honored tradition of passing off other people's work as their own.

One of OpenAI's math announcements a month ago claimed that their results cost only $2000 worth of tokens, which frustrated me because they were likely sweeping away many inconvenient details and almost certainly misrepresenting their true costs. But people took this as a gotcha. This is the same bullshit as the water usage arguments. We are literally seeing city council members signing motherfucking NDAs about this, and you think that water usage numbers provided by the tech companies themselves are going to sway me?

I am also questioning OpenAI's strategy of strip-mining math for PR, since it seems like advances in math do not actually register that well in the public. From what I remember, the Hugging Face incident got a lot more press than any of the math results.

Phil Aroneanu, Irreplaceable’s executive director and a co-founder of the climate organization 350.org, told me he believes that climate advocates initially floundered because they acted as policy wonks. They thought that making evidence-based arguments about the dangers of melting ice sheets and rising sea levels to receptive congresspeople would be enough to pass nationwide climate legislation. Today, Aroneanu said, movements are built not necessarily on what people think, but instead on what they feel. For climate, that meant fossil-fuel-divestment campaigns, protesting oil pipelines, and the school strikes led by Greta Thunberg. People are already “feeling the squeeze,” Aroneanu told me. “And we should be pointing that anxiety and that anger in the right direction.”

What is with this attitude of dismissing regular people's opinions as "feelings" in comparison to their own rationality? This is like those people who would really like to be anti-AI but find it more important to nitpick the water usage numbers and point out how agriculture uses so much more water anyway, in order to form a "better" opposition.

Some systems like SynthID (for Google's AI) get around this problem. In fact you don't need to know the LLM's internal state, and defeating it would likely involve breaking up most blocks of 3 words. The oversimplified explanation is that it introduces a function g that gives a score to each word, with the score being (pseudo)randomly determined by your secret key. For each next word the LLM generates, the LLM produces a small list of candidate next words, and the one with the highest score according to g is selected. You should expect that the LLM will generally pick words with a high score, but the score itself is independent of the LLM. To detect a watermark, you need to know g and the secret key, and you check if the average score is much higher than expected from normal text.

Now, one question is, will this bias to the LLM to favor certain words? The solution is that for each next word, you append the last 3 words (nothing special about 3, just a small number) to the secret key for g, and this repeatedly scrambles which words have a high score. To defeat the watermark, you would need to break up most blocks of 3 words. I'm sure there are deeper issues with this, but I have not studied the topic that much.

From a technical perspective, I don't really know how to let it track specific users. The goal is that if some AI vendor provides their key, it is easy for them to prove that their AI produced the text. So I guess if a user wanted to show that they generated the text, they could prove it. But usually AI users don't want people knowing that they used the slop cannon. In any case, Anthropic's own announcement states that their watermark does not contain identifying information for users.

In any case, some proud AI users are now frightened that there might be a way for people to identify that they use such a wonderful tool. How will I ever deliver low quality slop for my contracts now?

He said he uses AI for code reviews and translations, and worried an AI label on code shipped to clients could raise questions about authorship or trigger contract penalties.

Having code attributed to Claude "definitely would be not desirable," he said, as he would not want professionally shipped code to carry an invisible marker that could raise questions about authorship, compliance, or client policies.

My pet theory is that their reading comprehension has degraded, so this is all they can handle now.

Anthropic is now watermarking the outputs of its AI. For once this is some AI news that doesn't completely piss me off, and it's amusing to see all the uninformed boosters get in a tizzy about this.

I actually understand at a reasonable level how this watermarking works. A year ago, I watched Scott Aaronson give a talk about it, and from what I know he was somewhat involved in developing the theory behind it while working for OpenAI. But at the time my thought was, "He is naive if he thinks these companies would ever implement this out of the goodness of their hearts." And I was right; Anthropic is only doing watermarking now thanks to the EU AI Act, even though the theory has long been developed.

Watermarking doesn't mean adding an extra watermark that can be easily removed. It instead directly affects the output of the chatbot itself. Fundamentally, an LLM is still a most-likely-next-word-predictor. More precisely, an LLM produces a probability distribution of what the next word can be. For example, "my pet is a ..." could give a distribution of 60% dog, 30% cat, and 10% axolotl. Normally, an LLM would randomly choose the next word based on this distribution, and this is one reason why LLMs are nondeterministic (there's another parameter called "temperature" that affects this, but no need to get into that).

With watermarking, instead of a truly random choice, the randomness instead comes from a cryptographic pseudorandom generator seeded with a secret key from the AI company. If you don't know the secret key, then you can't really tell that watermarking was used. But if you do know the secret key, then the idea is you can tell when the text was generated by the LLM because you know exactly what word should be next. It would be a freak coincidence if some non-AI text just happened to choose the correct next word every time. Thus, you can provide a service to tell if some text was generated by the LLM. (This technically makes the LLM "deterministic", in a completely useless sense.)

Now, I think this is a step in the right direction, but it has its limits. The biggest problem is that you don't want people to just move to a different LLM without watermarking, and that's exhibit #832593 why government regulation is important. Another issue is that sometimes there is very little randomness in what the next word should be ("The first president of the USA is George ..."). Finally, watermarking can be defeated by editing the output, although you would have to break up most of the blocks of consecutive words. I have a feeling most AI users are not the type to put in extra effort after copy-pasting the output directly from the chat window.

I suppose it will discourage some of the "use cases" of LLMs, such as drowning the world with spam Slopstack essays. Ah, who am I kidding? Everyone could already tell it's AI generated, they don't care!
