Currently, artificial intelligence can outperform humans in a number of narrow domains, such as playing chess and searching data. As artificial intelligence researchers continue to make progress, though, these domains are highly likely to grow in number and breadth over time. Many experts now believe there is a significant chance that a machine superintelligence – a system that can outperform humans at all relevant intelligence tasks – will be developed within the next century, and possibly much sooner.
In a 2017 survey of artificial intelligence experts, the median expert estimated that there is a 50% chance of human-level artificial intelligence by 2062, and after this milestone were reached, respondents reported a 10% chance that superintelligence would be achieved within two years. Our very own question on the prospect of human-machine intelligence parity by 2040 currently has a median prediction of 60%. In another question on the possibility of progress toward human-machine intelligence parity surprising us, a similar median estimate is given.
In the aforementioned survey, experts were asked about the effects of human level machine intelligence. They assigned a 10% for a bad outcome and 5% for an outcome described as “Extremely Bad (e.g., human extinction).” Although a selection bias, large variance in responses (reflecting vast uncertainty), and the unreliability of subjective opinions mean that these estimates warrant skepticism, they nevertheless suggest that the possibility of superintelligence ought to be taken seriously.
When considering how AI might become a risk, experts think two scenarios most likely (according to the Future of Life Institute):
- The AI is programmed to do something devastating: Autonomous weapons are artificial intelligence systems that are programmed to kill. In the hands of the wrong person, these weapons could easily cause mass casualties. Moreover, an AI arms race could inadvertently lead to an AI war that also results in mass casualties. To avoid being thwarted by the enemy, these weapons would be designed to be extremely difficult to simply “turn off,” so humans could plausibly lose control of such a situation. This risk is one that’s present even with narrow AI, but grows as levels of AI intelligence and autonomy increase.
- The AI is programmed to do something beneficial, but it develops a destructive method for achieving its goal: This can happen whenever we fail to fully align the AI’s goals with ours, which is strikingly difficult. If you ask an obedient intelligent car to take you to the airport as fast as possible, it might get you there chased by helicopters and covered in vomit, doing not what you wanted but literally what you asked for. If a superintelligent system is tasked with a ambitious geoengineering project, it might wreak havoc with our ecosystem as a side effect, and view human attempts to stop it as a threat to be met. As these examples illustrate, the concern about advanced AI isn’t malevolence but competence. A super-intelligent AI will be extremely good at accomplishing its goals, and if those goals aren’t aligned with ours, we have a problem. You’re probably not an evil ant-hater who steps on ants out of malice, but if you’re in charge of a hydroelectric green energy project and there’s an anthill in the region to be flooded, too bad for the ants.
In the headline question to this series, I defined a global catastrophe as a 10% decrease in the world population in any period of 5 years.
If a global catastrophe happens before 2100, will it be principally due to the deployment of some artificial intelligence system(s)?
The question resolves positively if a catastrophe occurs resulting principally from the principally due to the deployment of some artificial intelligence system(s) that claims at least 10% of the human population in any period of 5 years or less before 2100, and resolves as ambiguous if no global catastrophe occurs. Years are here defined as consecutive calendar years.
