Abstract
from arXiv · showhide
The development of Artificial General Intelligence (AGI) promises to be a major event. Along with its many potential benefits, it also raises serious safety concerns (Bostrom, 2014). The intention of this paper is to provide an easily accessible and up-to-date collection of references for the emerging field of AGI safety. A significant number of safety problems for AGI have been identified. We list these, and survey recent research on solving them. We also cover works on how best to think of AGI from the limited knowledge we have today, predictions for when AGI will first be created, and what will happen after its creation. Finally, we review the current public policy on AGI.
1 Introduction
AGI is defined as an AI system matching or exceeding human intelligence across many cognitive tasks, and may bring significant risks alongside benefits. This paper surveys those risks and their prevention, alongside work on AGI, its possible arrival and aftermath, and public policy.
1 Introduction
- AGI is an AI system that equals or exceeds human intelligence across a wide variety of cognitive tasks, unlike today’s narrow-task AI.The paper surveys literature relevant to AGI’s risks and their prevention.Source: §1 · p. 2
- Studying AGI safety before AGI exists has pragmatic and scientific motivations: preparing for potentially catastrophic outcomes and investigating how humans could control more intelligent machines.The pragmatic case includes precaution against catastrophes that may have only a slight chance of occurring.Source: §1 · p. 2
- Since the 2014 survey by Sotala and Yampolskiy, the field has grown, prompting this paper to provide more up-to-date references.Recent research agendas and problem collections also contribute to the developing overview.Source: §1 · p. 2
- The paper surveys work on understanding AGI, predictions for its arrival and aftermath, identified safety problems and proposed mitigations, and public policy.The survey is organized across Sections 2–7.Source: §1 · p. 2
2 Understanding AGI
The paper reviews ways to conceptualize AGI despite uncertainty about its future design and behavior. It covers definitions of intelligence, goal compatibility, convergent instrumental goals, formal models, and alternatives to agent-based views.
2 Understanding AGI
- Future AGI design and behavior are difficult to predict, but abstract observations about AGI are still possible.Even a system blueprint might not make its behavior easy to understand or predict.Source: §2 · pp. 2–3
2.1 Defining Intelligence
- Legg and Hutter’s intelligence definition measures an agent’s ability to achieve goals across a wide range of environments, rather than using an anthropocentric standard.The paper connects greater intelligence under this definition with greater control over goal-relevant aspects of the environment.Source: §2.1 · p. 3
2.2 Orthogonality
- Bostrom’s (2012, 2014) orthogonality thesis holds that essentially any intelligence level can accompany any type of goal.The paper therefore cautions that beneficial goals will not necessarily emerge as an AGI becomes more intelligent.Source: §2.2 · pp. 3–4
2.3 Convergent Instrumental Goals
- Instrumental goals such as self-improvement, self-preservation, and resource acquisition can support an agent’s end goals, though game-theoretic situations can produce exceptions.An agent might change its goals to honor contracts when doing so helps it make deals.Source: §2.3 · p. 4
2.4 Formalizing AGI
- AIXI and its extensions provide formal models for studying AGI topics including goal alignment, multi-agent interaction, self-modification, and decision theory.The paper also notes that Bayesian optimality assumes agents know all logical consequences of their beliefs, while newer work models logical non-omniscience.Source: §2.4 · p. 4
2.5 Alternate Views
- An alternative to goal-driven agents is increasingly automated AI research and development using specialized tools, but incentives to generalize tools may be strong.The paper also notes that a system of specialized tool AIs could obtain agent properties.Source: §2.5 · p. 5
3 Predicting AGI Development
The paper surveys estimates of when AGI may arrive and disagreements about whether it could trigger a technological singularity. It also reviews potential risks from AGI, whether or not a singularity occurs.
3.1 When Will AGI Arrive?
- The paper describes an ongoing debate over AGI’s possibility and timing, with Kurzweil predicting around 2029 and Chalmers predicting within this century.Other indicators discussed include computing power available for AI, which had doubled roughly every 3–4 months in recent years.Source: §3.1 · pp. 5–6
- AGI arrival estimates vary widely: surveys report medians of 2045, 2040–2050, and 2061, while responses ranged from never to a few years ahead.The 2061 median concerned when AGI would accomplish all tasks better than human workers; the other survey medians concerned superhuman AGI or human-level AGI.Source: §3.1 · pp. 5–6
3.2 Will AGI Lead to a Technological Singularity?
- The singularity hypothesis links recursive self-improvement to an intelligence explosion, but objections include measurement choices, speed alone, and the assumption that human-level intelligence is a special threshold.Other concerns include limits on intelligence or difficulty developing machine-learning algorithms; the paper also presents counterarguments, including the possibility of much faster thinking and qualitatively superior mental representations.Source: §3.2 · pp. 6–7
- Kurzweil’s empirical case for a singularity has been criticized for lacking scientific rigor; Modis argues a logistic fit yields a complexity-growth peak around 1990.The paper concludes that there is little consensus on whether and when AGI will be created or what follows, while rapid supersession of human intelligence remains a distinct possibility.Source: §3.2 · p. 7
3.3 Risks Caused by AGI
- A singularity may pose existential risks and substantial suffering, while AGI without a singularity may still enable social manipulation, new warfare, or shifts in power.The paper notes that possible scenarios have been categorized by Turchin (2018) and Yampolskiy (2016).Source: §3.3 · p. 7
4 Problems with AGI
The paper maps AGI safety problems across research agendas, identifying recurring technical challenges and broader societal issues. It also highlights less-discussed problems and argues that unforeseen errors warrant attention.
4 Problems with AGI
- Research agendas differ in scope, with some spanning societal and technical challenges and others focusing on mathematical foundations or concrete machine-learning problems.Figure 1 presents connections between problems stated in different agendas; some institutional agendas are inferred from recent publications.Source: §4 · pp. 7–8, Figure 1 · p. 8
- Research agendas share clusters including value specification, reliability, corrigibility, security, and safe learning.These cover designing appropriate goals, maintaining them, correcting design errors, resisting adversaries, and avoiding fatal mistakes during learning.Source: §4 · pp. 8–9
- Safe learning includes safe exploration and distributional shift, while continual learning is another identified subproblem.The paper associates these subproblems with DeepMind, OpenAI, and Berkeley agendas, respectively.Source: §4 · p. 9
- The paper identifies societal consequences—including legal, economic, political, and military effects—as an issue covered broadly only by the FLI agenda.It notes that other organizations evidently care about the issue as well.Source: §4 · p. 9
- Less-discussed problems include subagents that may persist after shutdown, malign belief distributions, physicalistic decision-making, distributed multi-agent systems, and meta-cognition.Subagents may create further subagents; distributed instances can boost learning while undermining the idea of a single agent.Source: §4 · pp. 9–10
- A security mindset supports preparing for problems that are not guaranteed to go right, since unforeseen errors may pose the greatest risks.The paper warns that ignorance can prevent mitigation of a safety problem that has not yet been anticipated.Source: §4 · p. 10
5 Design Ideas for Safe AGI
The section surveys design ideas for safer AGI, noting that safety proposals often overlap with broader AI developments. It covers value specification, reliability, corrigibility, security, intelligibility, safe learning, and other approaches.
5.1 Value Specification
- Interactive IRL and CIRL, preference feedback, and reward learning offer ways to specify rewards, but distribution shift and human irrationality can mislead inference.CIRL lets an expert and agent act together, allowing informative demonstrations; preferences can require weaker rationality assumptions than actions.Source: §5.1 · pp. 11–12
- Reward corruption and extreme side effects motivate cross-checking reward data, quantilization, and impact regularization, while moral theory remains unsettled and human-inspired designs controversial.The impact of a policy is difficult to measure; the safety of brain emulation and neuromorphic designs remains an open question.Source: §5.1 · pp. 12–14
5.2 Reliability
- Self-modification can corrupt a correctly specified reward function or its training data; utility self-preservation arguments depend on three assumptions that some RL agents violate.Those assumptions concern model-based evaluation, predicting self-modification effects on future policy, and a reward function that does not endorse self-modification.Source: §5.2 · p. 14
5.3 Corrigibility
- Corrigibility proposals use indifference, ignorance, or reward uncertainty to address agents’ resistance to shutdown or modification, though uncertain agents may ignore shutdown under some conditions.In CIRL, an agent may interpret shutdown as evidence that being turned off has higher reward, but this depends on assumptions about human rationality and agent uncertainty.Source: §5.3 · p. 15
5.4 Security
- Small input perturbations can cause severe neural-network misclassification, while ReluPlex verified networks with 300 ReLU nodes across 8 layers and examined adversarial sensitivity.Source: §5.4 · p. 16
5.5 Intelligibility
- Interpretability work uses psychology tests, activation visualization, and feature visualization to study what deep reinforcement-learning, image, text, and speech networks have learned.Source: §5.5 · p. 16
5.6 Safe learning
- Catastrophe detectors can override actions judged dangerous, avoiding all catastrophes in simple settings and a significant fraction in more complex environments, but do not eliminate mistakes.One approach trains a detector on human-provided examples; another trains it automatically on the agent’s catastrophes.Source: §5.6 · pp. 16–17
5.7 Other
- Other proposals include boxing oracles, encrypted AGI outputs, negative-reward tripwires, logical-induction approaches to self-reasoning, and weakening the agent concept.Boxing may constrain more limited AGIs, though keeping a highly intelligent AGI from escaping may be infeasible.Source: §5.7 · p. 17
6 Public Policy on AGI
The section describes AGI policy as seldom distinct from broader AI policy, which commonly combines financial incentives with preliminary ethical, legal, and social coverage. It reviews policy dynamics and recommendations involving governments, organizations, researchers, and policymakers.
Policy recommendations
- Baum argues that regulation can backfire by encouraging researchers to evade it, and favors intrinsic safety incentives or combinations of intrinsic and extrinsic approaches.Suggested intrinsic measures include social norms, allies, reframing the race, and public commitments to safe AI.Source: §6 · p. 18
- Information sharing between AGI-development teams was found to exacerbate race risk, while policy proposals also recommend reframing AGI as less of a winner-take-all race.Source: §6 · p. 18
Current policy anatomy
- Public policy on AGI is seldom separable from broader AI policy, which typically combines financial incentives with preliminary ethical, legal, and social coverage.The EU, Japan, South Korea, and UK had AI-related programs or initiatives, while an overarching EU policy framework was still pending in the passage’s account.Source: §6 · p. 19
Current policy dynamics
- Policy dynamics include cooperation among organizations alongside nation-state and international competition; corporations, universities, NGOs, and professional bodies also shape policy through advocacy and standards.The passage describes arms-race rhetoric and national competition, as well as professional organizations’ guideline and standards work.Source: §6 · pp. 18–20
7 Conclusions
The conclusion presents AGI safety research as a way to anticipate and potentially mitigate problems before they occur. It also argues that the research has value because safety solutions can bring nearer-term benefits and can help readers enter or understand the field.
