AI Risk Introduction
(TLDR for this section, since it's 101 stuff that many readers will have already grokked: Misuse vs Mistake; Principal-Agent problem; Omohundro Drives; we need deep safety measures in addition to mundane methods. Jump to "Sleepy-Bot" if all that seems familiar.)
Earth is in peril. Humanity is on the verge of building machines capable of intelligent action that outstrips our collective wisdom. These superintelligent artificial general intelligences ("AGIs") are almost certain to radically transform the world, perhaps very quickly, and likely in ways that we consider catastrophic, such as driving humanity to extinction. During this pivotal period, our peril manifests in two forms.
The most obvious peril is that of misuse. An AGI which is built to serve the interests of one person or party, such as jihadists or tyrants, may harm humanity as a whole (e.g. by producing bioweapons or mind-control technology). Power tends to corrupt, and if a small number of people have power over armies of machines we should expect horrible outcomes.
The only solution to misuse is to ensure that the keys to the machine (once/if they exist) stay in the hands of wise, benevolent representatives, who use it only for the benefit of civilization. Finding such representatives, forming a consensus around trusting them, and ensuring they are the only ones with the power to do transformative things is a colossal task. But it is, in my view, a well-understood problem that we can, as a species, solve with sufficient motivation.
The far greater peril, in my view, is that of a mistake. The construction of superintelligent AI is a form of the principal-agent problem. We have a set of values and goals that are important to us, and we need to somehow impart those into the machine. If we were able to convey the richness of human values to an AI, we would have a "friendly AI" which acted in our true interests and helped us thrive.
However, this task is subtly hard, philosophically confused, technically fraught, and (at the very least) vulnerable to serious errors in execution. We should expect the first AGIs to have only a crude approximation of the goal they were trained to accomplish (which is, itself, likely only a subset of what we find valuable), with the severity of the difference growing exponentially with the complexity of the target.
If an agent has a goal that doesn't perfectly match that of their principal, then, as it grows in power and intelligence, it will increasingly shape the world towards its own ends, even at the expense of what the principal actually cares about. The chance of a catastrophe happening essentially on accident (from the perspective of the humans) only grows as AGIs proliferate and we consider superhuman economies and a world shaped increasingly by, and for, machines.
The history of human invention is one of trial and error. Mistakes are a natural part of discovery. Building a superintelligent agent with subtly wrong goals, however, is almost certainly a mistake worse than developing a new, hyper-lethal virus. An unaligned AGI will strategically act to accomplish its goals, and thus naturally be pulled to instrumentally convergent subgoals ("Omohundro Drives") such as survival, accumulation of resources, and becoming the dominant force on Earth.
To maximize its chance of success, it will likely try to pursue these things in secret, defending itself from modification and attack by pretending to be aligned until it has the opportunity to decisively win. (All of this should be familiar background; unfamiliar readers are encouraged to read other, more complete descriptions of the problem.)
To avoid the danger of mistakes, we need a way to exp...
