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: AGI safety from first principles: Conclusion, published by Richard Ngo on the AI Alignment Forum. Let’s recap the second species argument as originally laid out, along with the additional conclusions and clarifications from the rest of the report. We’ll build AIs which are much more intelligent than humans; that is, much better than humans at using generalisable cognitive skills to understand the world. Those AGIs will be autonomous agents which pursue long-term, large-scale goals, because goal-directedness is reinforced in many training environments, and because those goals will sometimes generalise to be larger in scope. Those goals will by default be misaligned with what we want, because our desires are complex and nuanced, and our existing tools for shaping the goals of AIs are inadequate. The development of autonomous misaligned AGIs would lead to them gaining control of humanity’s future, via their superhuman intelligence, technology and coordination - depending on the speed of AI development, the transparency of AI systems, how constrained they are during deployment, and how well humans can cooperate politically and economically. Personally, I am most confident in 1, then 4, then 3, then 2 (in each case conditional on all the previous claims) - although I think there’s room for reasonable disagreement on all of them. In particular, the arguments I’ve made about AGI goals might have been too reliant on anthropomorphism. Even if this is a fair criticism, though, it’s also very unclear how to reason about the behaviour of generally intelligent systems without being anthropomorphic. The main reason we expect the development of AGI to be a major event is because the history of humanity tells us how important intelligence is. But it wasn’t just our intelligence that led to human success - it was also our relentless drive to survive and thrive. Without that, we wouldn’t have gotten anywhere. So when trying to predict the impacts of AGIs, we can’t avoid thinking about what will lead them to choose some types of intelligent behaviour over others - in other words, thinking about their motivations. Note, however, that the second species argument, and the scenarios I’ve outlined above, aren’t meant to be comprehensive descriptions of all sources of existential risk from AI. Even if the second species argument doesn’t turn out to be correct, AI will likely still be a transformative technology, and we should try to minimise other potential harms. In addition to the standard misuse concerns (e.g. about AI being used to develop weapons), we might also worry about increases in AI capabilities leading to undesirable structural changes. For example, they might shift the offense-defence balance in cybersecurity, or lead to more centralisation of human economic power. I consider Christiano’s “going out with a whimper” scenario to also fall into this category. Yet there’s been little in-depth investigation of how structural changes might lead to long-term harms, so I am inclined to not place much credence in such arguments until they have been explored much more thoroughly. By contrast, I think the AI takeover scenarios that this report focuses on have received much more scrutiny - but still, as discussed previously, have big question marks surrounding some of the key premises. However, it’s important to distinguish the question of how likely it is that the second species argument is correct, from the question of how seriously we should take it. Often people with very different perspectives on the latter actually don’t disagree very much on the former. I find the following analogy from Stuart Russell illustrative: suppose we got a message from space telling us that aliens would be landing on Earth sometime in the next century. Even if there’s doubt about the veracity of the message...
