I don't think I am. I have cited ROME as an early example of weight editing in large language models, the research has moved on since then. I think you are misinformed or don't know what has been done previously and extrapolating the results in this paper. In exp 1, you can recover a lot of the game geometry simply by visualizing the first-layer weights with numpy, which I actually did this morning, while reading the paper. In exp 2, the shapes are visible in the output-layer weights. The authors themselves acknowledge that these experiments exploit this.
For 3, Astra uses Python scripts to run the analysis using head-composition techniques from the Transformer Circuits thread, once again authors acknowledge this.
In 5 and 6, the model designs game strategies and implements them as neural weights, we already know that models can do the design for simpler policies and Go heuristics are very familiar which the model first implements with python , program-to-weight compilation has substantial prior work, including Tracr (2023), a paper I particularly like: https://arxiv.org/abs/2301.05062. What matters here is automating the process rather than a new method.
So "no human and no technology so far" makes no sense here, if you read the research. All of this is supported either by their experiment setup and citations, or prior work.
Aside from that, I think it is ironic that you cite a solution to the Navier-Stokes equation as some counterpoint to brute force, when that solution was found by scaling the agent swarm to massive proportions with tools and massive parallel exploration of that space, augmented by prior research on the subject.
To be clear, I think it is a cool work, but I think the part that matters is that at these smaller scales a current SOTA general purpose LLM can autonomously (and with help) apply these techniques or a form of them. That's worth investigating, I conjecture it is due to specialized post training on a custom RL env for mech interp.
