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: LLM Generality is a Timeline Crux, published by eggsyntax on June 24, 2024 on LessWrong. Short Summary LLMs may be fundamentally incapable of fully general reasoning, and if so, short timelines are less plausible. Longer summary There is ML research suggesting that LLMs fail badly on attempts at general reasoning, such as planning problems, scheduling, and attempts to solve novel visual puzzles. This post provides a brief introduction to that research, and asks: Whether this limitation is illusory or actually exists. If it exists, whether it will be solved by scaling or is a problem fundamental to LLMs. If fundamental, whether it can be overcome by scaffolding & tooling. If this is a real and fundamental limitation that can't be fully overcome by scaffolding, we should be skeptical of arguments like Leopold Aschenbrenner's (in his recent 'Situational Awareness') that we can just 'follow straight lines on graphs' and expect AGI in the next few years. Introduction Leopold Aschenbrenner's recent 'Situational Awareness' document has gotten considerable attention in the safety & alignment community. Aschenbrenner argues that we should expect current systems to reach human-level given further scaling and 'unhobbling', and that it's 'strikingly plausible' that we'll see 'drop-in remote workers' capable of doing the work of an AI researcher or engineer by 2027. Others hold similar views. Francois Chollet and Mike Knoop's new $500,000 prize for beating the ARC benchmark has also gotten considerable recent attention in AIS[1]. Chollet holds a diametrically opposed view: that the current LLM approach is fundamentally incapable of general reasoning, and hence incapable of solving novel problems. We only imagine that LLMs can reason, Chollet argues, because they've seen such a vast wealth of problems that they can pattern-match against. But LLMs, even if scaled much further, will never be able to do the work of AI researchers. It would be quite valuable to have a thorough analysis of this question through the lens of AI safety and alignment. This post is not that[2], nor is it a review of the voluminous literature on this debate (from outside the AIS community). It attempts to briefly introduce the disagreement, some evidence on each side, and the impact on timelines. What is general reasoning? Part of what makes this issue contentious is that there's not a widely shared definition of 'general reasoning', and in fact various discussions of this use various terms. By 'general reasoning', I mean to capture two things. First, the ability to think carefully and precisely, step by step. Second, the ability to apply that sort of thinking in novel situations[3]. Terminology is inconsistent between authors on this subject; some call this 'system II thinking'; some 'reasoning'; some 'planning' (mainly for the first half of the definition); Chollet just talks about 'intelligence' (mainly for the second half). This issue is further complicated by the fact that humans aren't fully general reasoners without tool support either. For example, seven-dimensional tic-tac-toe is a simple and easily defined system, but incredibly difficult for humans to play mentally without extensive training and/or tool support. Generalizations that are in-distribution for humans seems like something that any system should be able to do; generalizations that are out-of-distribution for humans don't feel as though they ought to count. How general are LLMs? It's important to clarify that this is very much a matter of degree. Nearly everyone was surprised by the degree to which the last generation of state-of-the-art LLMs like GPT-3 generalized; for example, no one I know of predicted that LLMs trained on primarily English-language sources would be able to do translation between languages. Some in the field argued as...
