I think (as do others) that advanced AI could have really big undesired impacts like causing the extinction of people. I also think, with higher confidence, that advanced AI is likely to have some large impacts on the way that people live, without saying exactly what these impacts are likely to be. AI X-risk seems to be regarded as one of the most important potential impacts for AI safety researchers to focus on, particularly by people who think that promoting a long and prosperous future for humans and other living things is a top priority. Considering the amount of work on AI X-risk overall (not just within EA), should a lot more attention be given to AI X-risk? What other AI impacts should receive a lot more attention alongside X-risk?
I am interested in impacts that are explained in a manner that is nearly concrete enough to be the subject of a prediction tournament or prediction market, though some flaws are acceptable. For example, the impact "AI causes the extinction of people in the next 1000 years" has at least two flaws from the point of view of a prediction tournament: first, establishing that AI is responsible for an extinction event might not be straightforward, and second if people are extinct then there will be on one to resolve the question. However, it's concrete enough for my purposes.
Please propose impacts as an answer to this question, and only propose one potential impact per answer. You can also include reasons why you think the identified impact is a priority. If you want to discuss multiple impacts, or say something other than proposing an impact to consider, please post it as a comment instead. And, to reiterate, I'm interested in impacts you think should receive more attention overall, not just more attention within the EA community.
It should be mentioned that all (or at least most) ideas to survive the heat death of the universe involve speculative physics. Moreover, you have to deal with infinities. If everyone is suffering but there is one sentient being that experiences a happy moment every million years, does this mean that there is an infinite amount of suffering and an infite amount of happiness and the future is of neutral value? If any future with an infinite amount of suffering is bad, does this mean that it is good if sentient life does not exists forever? There is no obvious answer to these questions.
