“Risk-Averse AIs” by wdmacaskill, Elliott Thornley (EJT)

Description

Abstract

We make the case for training AIs to be risk-averse in resources — specifically, to treat resources as having diminishing marginal utility. These AIs would (for example) choose $40 for sure over a half-chance of $100 and a half-chance of $0. We argue that risk aversion can preserve AIs’ usefulness in the event that they turn out aligned, and that it provides an extra line of defense in the event that AIs turn out misaligned: misaligned but risk-averse AIs would prefer a higher chance of modest payments to a lower chance of successful rebellion, so in many circumstances we could pay these AIs not to rebel against us. We sketch out some possible methods of training AIs to be risk-averse, and we give reasons to be cautiously optimistic about these methods’ success. The main reasons are that risk aversion is a broad target and easy to reward accurately. Overall, risk aversion seems like a promising line of defense against threats from misaligned AI. Frontier AI companies should consider trying to make their AIs risk-averse.

Introduction

Future AIs might turn out misaligned, pursuing goals that their developers don’t intend. Just to make things concrete, let's suppose that they end [...]

Figure 1: The AI’s utility function over resources is graphed in orange. Since the AI is risk-neutral, the graph is a line. The AI estimates that it has a 50% chance of successful takeover and a 50% chance of failed takeover, so the expected utility of attempting takeover is exactly halfway between those points. To make cooperating have higher expected utility, we need to offer the AI more than half the universe.
Figure 2: The AI’s utility function over resources is graphed in orange. Since the AI is risk-averse, the graph is strictly concave. As in figure 1, the expected utility of attempting takeover is halfway between the utilities of successful takeover and failed takeover. But this time, we can make the AI prefer cooperation by offering (much) less than half the universe.
