We build what I called a modest superintelligence, consisting of one or more humans who are naturally extremely intelligent or who underwent intelligence amplification, they figure out how to build a stable world government and decide that it's safer to do WBE and gradually increase human (em) intelligence than to build an FAI.
Safely and gradually enhancing human intelligence is hard. I agree that a team of human geniuses with unlimited time and resources could probably do it. But you need orders of magnitude more resources and thinking time than the fools "trying" to make UFAI.
A genetics project makes a lot of very smart babies, they find it hard to indoctrinate them, while educating them enough, while producing diversity. Militaristic bootcamp will get them all marching in line, and squash out most curiosity and give little room for skill. Handing them off to foster...
Yes, the most likely outcome: people develop increasingly more capable intelligence capabilities as extensions of themselves in a pluralistic society, without any one entity obtaining monopolistic control. Society continues as-is, but with posthuman capabilities.
as extensions of themselves
Lets assume that AI doubling time is fairly slow (eg 20 years) and very widely distributed. Huge numbers of people throw together AI systems in garages. If the basic problems of FAI haven't been solved, you are going to get millions of paperclip maximizers. (Well, most of them will be optimising different things) 100 years later, humanity, if it still exists at this point are pawns on a gameboard that contains many superintelligences. What happens depends on how different the superintelligences goals are, and how hard it is...
This seems like one potential path, but for it to work, you would need a government structure that can survive without successful pro AI revolutionaries for a billion years. You also need law enforcement good enough to stop anyone trying to make UFAI, with not a single failure in a billion years. As for a SAI that will help us stop UFAI, can explain 1) how it would help and 2) how it would be easier to build than FAI?
You also need to say what happens with evolution, given this kind of time, and non ancestral selection pressures, evolution will produce beings not remotely human in mind or body. Either argue that the evolution is in a morally ok direction, and that your government structure works with these beings, or stop evolution by selective breeding - frozen samples - genetic modification towards some baseline. Then you just need to say how all human populations get this, or how any population that doesn't won't be building UFAI.
I have no comment on how plausible either of these scenarios are. I'm only making the observation that long term good futures not featuring friendly AI require some other mechanism preventing UFAI from happening. Either SAI in general would have to be implausible to create at all, or some powerful actor such as a government or limited AI would have to prevent it.
Does anyone know any potential long term futures that are good, and do not involve the creation of a friendly super-intelligence.
To be clear, long term future means billion years+. In most of my world models, we settle into a state from which it is much easier to predict the future within the next few hundred years. (Ie a state where it seems unlikely that anything much will change)
By good, I mean any future that you would prefer to be in if you cared only about yourself, or would be replaced with a robot that would do just as much good here. A weaker condition would be any future that you would want not to be erased from existence.
A superintelligent agent running around doing whatever is friendly or moral or whatever would meet these criteria, I am excluding it because I already know about that possibility. Your futures may contain Superintelligences that aren't fully friendly. A superintelligence that acts as a ZFC oracle is fine.
Your potential future doesn't have to be particularly likely, just remotely plausible. You may assume that a random 1% of humanity reads your reply and goes out of their way to make that future happen. Ie people optimizing for this goal can use strategies of the form "someone does X" but not "everyone does X". You can get "a majority of humans does X" if X is easy to do and explain and most people have no strong reason not to X.
You should make clear what stops somebody making a UFAI which goes on to destroy the world. (Eg paperclip maximizer)
