It is very clear what it means to align an agent:
It is less clear what it means to align an LLM:
Probably, we should have different alignment goals for different deployment cases: LLM assistants should say nice and harmless things, while agents that help automate alignment research should be free to think anything they deem useful, and reason about the harmlessness of various actions “out loud” in their CoT, rather than implicitly in a forward pass.
I think even your definition of what it means for an agent to be aligned is a bit underspecified because it doesn't distinguish between two possibilities:
Is the agent creating positive outcomes because it trades and compromises with us, creating a mutually beneficial situation that benefits both us and the agent, or
Is the agent creating positive outcomes because it inherently "values what we value", i.e. its utility function overlaps with ours, and it directly pursues what we want from it, with no compromises?
Definition (1) is more common in the human world. We say that a worker is aligned with us if they do their job as instructed (receiving a wage in return). Definition (2) is more common in theoretical discussions of AI alignment, because people frequently assume that compromise is either unnecessary or impossible, as a strategy that we can take in an AI-human scenario.
By itself, the meaning you gave appears to encompass both definitions, but it seems beneficial to clarify which of these definitions you'd consider closer to the "spirit" of the word "aligned". It's also important to specify what counts as a good outcome by our values if these things are a matter of degree, as opposed to being binary. As they say, clear thinking requires making distinctions.
I want to formulate what emotions are from the perspective of an observer that has no emotions itself. Emotions have a close relationship with consciousness, and similar to the hard problem of consciousness, it is not obvious how to know what another mind feels like. It could be that one person perceives emotions 1000x as strong as another person, but the two different emotional experiences lead to exactly the same behavior. Or it could be that one species perceives emotions on a different intensity scale than another one. This creates a challenge for utilitarians: if you want to maximize the happiness of all beings in the universe, you need a way of aggregating happiness between beings.
So, how can we approach this question? We can start by trying to describe the observable properties of emotions as good as we can:
My intermediate conclusion is that emotions likely evolved because they are computationally efficient proxies for how good the current state is and how to spend energy. They can be viewed as latent variables that often yielded fitness-increasing behavior, whose impact extends beyond the situations in which it actually proves useful - for example, when I get grumpy because I’m hungry.
If this is true, emotions are more useful when a being is less capable of abstract reasoning, therefore less intelligent animals might experience emotions stronger rather than weaker. This fits with the observation that intelligent humans can reduce their suffering via meditation, or that pets seem to suffer more from getting a vaccine than adult humans. However this is a bit of a leap and I have low confidence in it.
Regarding digital sentience, this theory would predict that emotions are more likely to emerge when optimization pressure exists that lets an AI decide how to spend energy. This is not the case in language model pretraining, but is the case in most forms of RL. Again, I am not very confident in this conclusion.
