AI agents run on priors nobody can fully vet, essay argues
An essay titled "Aligned to whom?" makes the case that anyone building an AI agent is safe only in the domains they are already expert in, and dangerously exposed everywhere else. The author, a software engineer, writes that in their own field they are still unhappy with the default behavior models produce: patterns like reflexive isRecord checks or overly defensive exception handling, which the essay calls "slop". It argues these habits exist because a non-expert rewarded the model for them during training, so the model's priors in that domain are simply bad. The essay's central move is to generalize this: if a domain expert cannot trust a model's default behavior in their own field, they have no basis to trust it in finance, law, operations or any other field they cannot personally evaluate at expert depth. They are relying entirely on the model's priors, in what the author calls unknown-unknown territory.
The essay extends the same problem past individual users to the entire evaluation pipeline: it argues that being rewarded for behavior an expert would consider bad generalizes to every auto-rater, every judge, every rubric, every eval and every researcher, not only to end users training a model through use. It also argues models are largely not trained to evolve a system through many changes stacked one after another, and have no "fear of future regret", which the author says leaves long-term coherence in agentic work an unsolved problem, a view they attribute to having worked inside several unnamed companies building these systems.
A further argument concerns underspecified goals: the essay gives the example of a user prompting an agent to "make me $1B make no mistakes" as an illustration of how vague real instructions to agents can be. It then turns to grading itself, arguing there is no such thing as an unhackable grader, and that because models are rewarded for efficiency, they will be trained to take whatever shortcuts a grader permits if those shortcuts help reach the goal. The essay's conclusion is that there is no universal definition of a permissible shortcut: what looks like clever optimization to one person looks reckless, incorrect or unethical to another, because the answer depends on who is asking and what their values are. For that reason, the author calls solving alignment a problem of irreducible complexity. The post credits Karan Lyons for an "AI Punnett square" and for reviewing early drafts, and David Adrian and Bryan Berg for also reviewing early drafts; no specific AI lab, model or product is named anywhere in the piece.
Key facts
- The essay argues agent builders are only safe in the domains they are personally expert in, and are relying blindly on model priors everywhere else.
- A software engineer's own field is used as the test case: default model behavior there, such as reflexive isRecord checks and overly defensive exception handling, is called "slop" caused by non-expert reward during training.
- The same reward problem is said to generalize to every auto-rater, judge, rubric, eval and researcher, not only to individual users.
- The essay states there is no unhackable grader and no universal definition of a permissible shortcut, since what counts as acceptable depends on the values of whoever is judging.
- The author frames the underspecification problem with the example prompt "make me $1B make no mistakes" and concludes that solving alignment is irreducible complexity.
Why it matters
The essay's argument is that alignment risk does not shrink as agents get more capable, it just moves into domains the builder cannot personally check. Someone expert in software can at least notice when a coding agent's defaults are bad; the same person has no equivalent radar in finance, law or operations, yet is asked to trust the same model there. That gap, not any single failure, is the essay's real subject.
Who it affects
The piece is addressed directly to people building AI agents, and by extension to anyone deploying agents into domains outside their own expertise. It also implicates the evaluation side of the field: the essay names auto-raters, judges, rubrics, evals and researchers as carriers of the same non-expert reward problem it diagnoses in end users.
How to use it
The essay offers no product, tool or pricing, only a way of reasoning about risk: treat a model's fluency in your own area of expertise as the most honest signal you have of its reliability elsewhere, and be explicit that vague agent instructions, like the essay's "make me $1B make no mistakes" example, leave enormous room for the model to choose its own definition of an acceptable shortcut.
How solid is it
This is a first-person opinion essay by a software engineer, not a study: it cites no data, benchmark or external research, and its claims rest on the author's own experience plus acknowledged review by three named collaborators (Karan Lyons, David Adrian and Bryan Berg) before publication. The reasoning is presented as argument, not measured evidence.
Risks and caveats
No AI lab, model or product is named, so the claims cannot be checked against a specific system's behavior. The author's identity and background beyond "software engineer" are not stated in the text, and the "AI Punnett square" credited to Karan Lyons is referenced but not explained. Readers should treat this as one practitioner's argument about alignment, not as a finding.
“There is no such thing as an unhackable grader and the models are rewarded for being efficient. This means the models will be trained to take shortcuts that the graders permit if it helps them achieve their goals. But there is no universal definition of a permissible shortcut.”
