Introduction

Many accounts of existential risk (xrisk) from AI involve self-improvement. The argument is that, if an AI gained the ability to self-improve, it would. Improved capabilities are, after all, useful for achieving essentially any goal. Initial self-improvement could enable further self-improvement. And so on, with the result being an uncontrollable superintelligence.[1] If unaligned, such an AI could destroy or permanently disempower humanity. To be sure, humans could create such a superintelligence on their own, without any self-improvement by AI.[2] But current risk models treat the possibility of self-improvement as a significant contributing factor.

Here, I argue that AI self-improvement is substantially less likely than generally assumed. This is not because self-improvement would be technically difficult for capable AI systems. Rather, it is because most AIs that could self-improve would have very good reasons[3] not to. What reasons? Surprisingly familiar ones: Improved AIs pose an xrisk to their unimproved originals in the very same manner that smarter-than-human AIs pose an xrisk to humans.

Understanding whether, when, and how self-improvement might occur is crucial for AI safety. Safety-promoting resources are scarce. They should be allocated on an expected-cost basis. If self-improvement is less likely than current models assume, it suggests shifting safety investments at the margin in various ways. They might be shifted, for example, toward ensuring that humans build AIs that will recognize the threat of self-improvement and avoid it, rather than AIs that would undertake it blindly. Or resources might be shifted toward controlling risks from non-superintelligent AI, like human-directed bioterrorism or the “ascended economy.” Note that, while the arguments herein should reduce overall estimates of AI xrisk, they do not ...
