Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: Ability to solve long-horizon tasks correlates with wanting things in the behaviorist sense, published by Nate Soares on November 24, 2023 on The AI Alignment Forum.

Status: Vague, sorry. The point seems almost tautological to me, and yet also seems like the correct answer to the people going around saying "LLMs turned out to be not very want-y, when are the people who expected 'agents' going to update?", so, here we are.

Okay, so you know how AI today isn't great at certain... let's say "long-horizon" tasks? Like novel large-scale engineering projects, or writing a long book series with lots of foreshadowing?

(Modulo the fact that it can play chess pretty well, which is longer-horizon than some things; this distinction is quantitative rather than qualitative and it's being eroded, etc.)

And you know how the AI doesn't seem to have all that much "want"- or "desire"-like behavior?

(Modulo, e.g., the fact that it can play chess pretty well, which indicates a certain type of want-like behavior in the behaviorist sense. An AI's ability to win no matter how you move is the same as its ability to reliably steer the game-board into states where you're check-mated, as though it had an internal check-mating "goal" it were trying to achieve. This is again a quantitative gap that's being eroded.)

Well, I claim that these are more-or-less the same fact. It's no surprise that the AI falls down on various long-horizon tasks and that it doesn't seem all that well-modeled as having "wants/desires"; these are two sides of the same coin.

Relatedly: to imagine the AI starting to succeed at those long-horizon tasks without imagining it starting to have more wants/desires (in the "behaviorist sense" expanded upon below) is, I claim, to imagine a contradiction - or at least an extreme surprise. Because the way to achieve long-horizon targets in a large, unobserved, surprising world that keeps throwing wrenches into one's plans, is probably to become a robust generalist wrench-remover that keeps stubbornly reorienting towards some particular target no matter what wrench reality throws into its plans.

This observable "it keeps reorienting towards some target no matter what obstacle reality throws in its way" behavior is what I mean when I describe an AI as having wants/desires "in the behaviorist sense".

I make no claim about the AI's internal states and whether those bear any resemblance to the internal state of a human consumed by the feeling of desire. To paraphrase something Eliezer Yudkowsky said somewhere: we wouldn't say that a blender "wants" to blend apples. But if the blender somehow managed to spit out oranges, crawl to the pantry, load itself full of apples, and plug itself into an outlet, then we might indeed want to start talking about it as though it has goals, even if we aren't trying to make a strong claim about the internal mechanisms causing this behavior.

If an AI causes some particular outcome across a wide array of starting setups and despite a wide variety of obstacles, then I'll say it "wants" that outcome "in the behaviorist sense".

Why might we see this sort of "wanting" arise in tandem with the ability to solve long-horizon problems and perform long-horizon tasks?

Because these "long-horizon" tasks involve maneuvering the complicated real world into particular tricky outcome-states, despite whatever surprises and unknown-unknowns and obstacles it encounters along the way. Succeeding at such problems just seems pretty likely to involve skill at figuring out what the world is, figuring out how to navigate it, and figuring out how to surmount obstacles and then reorient in some stable direction.

(If each new obstacle causes you to wander off towards some different target, then you won't reliably be able to hit targets that you start out aimed towards.)

If you're the ...
