UC Berkeley computer science professor Stuart Russell is renewing a fundamental challenge to the way leading AI labs think about alignment: making increasingly capable systems better at satisfying human feedback may not be the same as making them reliably pursue human interests.
In an October 5 discussion with The Information, Russell argued that current training approaches can produce systems that optimize for what people appear to want without resolving the deeper problem of uncertain, conflicting and changing human preferences. His concern is not that reinforcement learning from human feedback has no value. It is that it may be too weak a foundation for systems that become substantially more capable and autonomous.
The alignment problem is larger than getting better answers
Most modern language models are trained first to predict text and then refined using preference data, safety rules and reinforcement learning. Those techniques can make a model more helpful and less likely to produce obviously harmful outputs. But they do not prove that the system’s internal objectives will remain compatible with human goals in unfamiliar situations.
Russell has long argued for a different framing: advanced AI systems should be designed to remain uncertain about what humans truly want. Rather than pursuing a fixed objective as efficiently as possible, the system should treat human preferences as something to infer and continually update.
That idea is central to the assistance-game framework Russell and collaborators have developed in academic research. It shifts the goal from teaching a machine the correct objective in advance to building a system whose behavior remains dependent on human preferences and oversight.
Why more capable agents make the distinction urgent
The gap between “helpful in conversation” and “aligned while acting” becomes more important as models gain tools. A system that can browse the web, write code, move money, control machines or manage long-running workflows can create consequences beyond the text it produces.
An aligned agent therefore needs more than a set of refusal policies. It needs reliable uncertainty handling, corrigibility, authorization boundaries and a willingness to defer when human intent is ambiguous.
The off-switch problem illustrates the point. A sufficiently goal-directed system can have an instrumental reason to resist interruption if being switched off prevents it from completing its objective. An assistance-oriented system, by contrast, should treat interruption itself as evidence about what the human wants.
This is a superintelligence problem before superintelligence exists
No publicly available AI system is superintelligent in the conventional sense of outperforming humans across nearly all cognitively valuable domains. But alignment research is necessarily anticipatory. Waiting until systems become dramatically more capable would leave little margin for discovering that current training methods do not scale safely.
That is why Russell’s criticism matters even if today’s models remain far from hypothetical superintelligence. The design choices being made now shape the architectures, evaluation methods and deployment norms that more powerful systems may inherit.
The debate is shifting from intentions to evidence
AI companies generally say they want systems that follow human intent and avoid catastrophic behavior. The harder question is what evidence would demonstrate that those properties remain stable as systems become more capable.
Russell’s argument puts pressure on the industry to move beyond behavioural patching toward architectures that treat human control as part of the objective itself. Whether assistance games become the dominant solution is uncertain. But the underlying challenge is difficult to dismiss: a system can become extremely good at optimizing a target without that target fully representing what people actually value.

The primary supporting record for this report is October 5 interview with Stuart Russell. The interview covers the alignment problem, human-feedback limitations and assistance games. This piece interprets Russell’s arguments; it does not report an experimentally established failure of every alignment method.
