One point worth making is that any society would believe they had made moral progress over time, regardless of their history. If you had two societies, and one started at point A and moved to point B, and the other moved from B to A, both would feel they had made moral progress.
Not necessarily. If A was a Nash equilibrium while B was a Pareto improvement from that but the second society couldn't coordinate to achieve it, then they could gaze wistfully into the past, say they had fallen, and be right to do so.
This is a little dusty now, and was originally an attempt to collect what others had said was problematic with CEV, without passing judgement over whether I thought that was a good or a bad concern. So it has the advantage of being very comprehensive.
It also contains a summary of CEV for your convenience.
People talk as if inconsistencies and contradictions in our value systems mean the whole enterprise of emulating human morality is worthless. Of course human value systems are contradictory; you can still implement a contradictory value system if you're willing to accept the occasional mis-calculation.
A deeper problem, in my opinion, is the nature of our behavior. It seems that in a lot of situations people make decisions first then justify them later, often subconsciously. The only way to accurately emulate this is to have a machine that also first makes ...
If human values are not coherent, is that not a problem for any plans we might have for the future, rather than just CEV?
If human values are not capable of becoming coherent, and humanity comes to know that, what should be done?
@Nozick: we are plugged to machine (Internet) and virtual realities (movies, games). Do we think that it is wrong? Probably it is question about level of connection to reality?
@Häggström: there is contradiction in definition what is better. F1 is better than F because it has more to strive and F2 is better than F1 because it has less to strive.
@CEV: time is only one dimension in space of conditions which could affect our decisions. Human cultures are choosing cannibalism in some situations. SAI could see several possible future decisions depending on sur...
Is CEV intended to be specified in great technical depth, or is it intended to be plugged into a specification for an AI capable of executing arbitrary natural language commands in a natural language form?
Would it be so bad to lock in our current values? (e.g. Compared to the other plausible dangers inherent in a transition to AI?)
ethics is just the heuristics genes use to get themselves copied. we're all trying to maximize our own expected utility, but since none of us wants to let any others become a dictator, there is a game theoretical equilibrium where we agree to have rules like "murder is illegal" because even though it stops me from murdering you, it also stops you from murdering me. our rational goal is to shrink the circle of people included in this decision to the smallest possible group that includes ourselves. hence why we wouldn't want to sacrifice our own interests fo...
If CEV produces whatever people value, do you think it would produce the above because you have different values than other people... ?
Yes. And thank you for phrasing it that way so I understand that is at least one explanation for my concern.
It seems beyond likely to me that the CEV you get will depend heavily on just who you include in your definition of "humans" whos volition must be considered in defining CEV. Even if CEV were intended to be just that subset of volitions that "everybody" would agree on (if they were smart enough), will your definition of everybody include paranoid schizophrenics? People born with severely deformed brains? Sociopaths? Republicans? The French? My point being that our intuition is of a "common definition of human we can all agree on" but the reality of 7 billion live humans plus a few billion easy to anticipate might have a non-intuitively large variation across its volition.
So if CEV includes a "veto power" in its definition granted to all humans defined broadly enough to include sociopaths, we lose many of the values that allow us to work cooperatively.
Further concerning me, I think it is likely that humanity benefits from a diversity in values. At one level, societies with different values have different levels of success under different challenges, and in something like survival of the fittest, the societies that thrive have values that work better than those that don't. At another level, within a society diversity in values serves the group: the nurturers are caretakers, the nerds technologists, the sociopaths become leaders and work in security.
CEV as I have heard it described sounds like a core of values, a kernel that all FAI operating systems would have to include. It doesn't sound like a set of values or a core of meta-values that would somehow incorporate in a single kernel all the variation in values that has served humanity so well.
So yes, I am concerned that CEV is impossible, but perhaps not provably impossible, that any actual attempts to build a CEV will have more to do with the values of the people building CEV rather than some undefinable generalization of humanity.
Another concern: AI with a CEV constraint will necessarily be less adaptable than AI with no CEV constraint. So in the absence of complete totalitarian control over where AI can come from, non-CEV AI once created would eventually out-compete CEV-based AI anyway, and all that effort would have been for naught.
Finally, what I think of as a Kurzweilian paradigm of AI makes more sense to me than the idea of independent AIs that exist separately from humans. Kurzweil seems to me talks more of enhancing existing humans, building on modules, interfacing us better, and so on. Eventually, perhaps, the enhanced human is 99% enhancement and 1% human and so it becomes a matter of attitude whether you still think of it as human. Do you think CEV is something that applies to building up enhanced humans (instead of independent entities)?
Also, it seems to me that avoiding a new technology (CEV) specifically because it will make your life too easy has a lot in common with living in a false world which is centuries out of date.
The ultimate technology that makes my life too easy is wireheading. That was just fun to say, I don't actually recognize it as a great response to your point, but I throw it out there because there might be more to it than I am allowing.
I suppose one man's dystopia is another woman's brave new world. I don't think being locked in the matrix by FAIs who know this is the way to keep us safe is something I reject because it is too easy. I reject it because it is essentially wireheading.
My main concern about CEV is that it winds up protecting us from nothing, that it was a waste of time and effort. But this does go along with my belief that any CEV would be one that would not incorporate my values around the importance of diversity in values, and my values around being able to reject and fight violently against other humans that had values that I found sufficiently threatening to my values.
I appreciate the questions, it is nice to sharpen my ideas a little bit. I admit I have hardly sharpened them to a mathematical precision by any means, but if you see any obvious intuition pumps working against me, I'd love to hear them.
This is part of a weekly reading group on Nick Bostrom's book, Superintelligence. For more information about the group, and an index of posts so far see the announcement post. For the schedule of future topics, see MIRI's reading guide.
Welcome. This week we discuss the twenty-third section in the reading guide: Coherent extrapolated volition.
This post summarizes the section, and offers a few relevant notes, and ideas for further investigation. Some of my own thoughts and questions for discussion are in the comments.
There is no need to proceed in order through this post, or to look at everything. Feel free to jump straight to the discussion. Where applicable and I remember, page numbers indicate the rough part of the chapter that is most related (not necessarily that the chapter is being cited for the specific claim).
Reading: “The need for...” and “Coherent extrapolated volition” from Chapter 13
Summary
Another view
Part of Olle Häggström's extended review of Superintelligence expresses a common concern—that human values can't be faithfully turned into anything coherent:
Notes
1. While we are on the topic of critiques, here is a better list:
In-depth investigations
If you are particularly interested in these topics, and want to do further research, these are a few plausible directions, some inspired by Luke Muehlhauser's list, which contains many suggestions related to parts of Superintelligence. These projects could be attempted at various levels of depth.
If you are interested in anything like this, you might want to mention it in the comments, and see whether other people have useful thoughts.
How to proceed
This has been a collection of notes on the chapter. The most important part of the reading group though is discussion, which is in the comments section. I pose some questions for you there, and I invite you to add your own. Please remember that this group contains a variety of levels of expertise: if a line of discussion seems too basic or too incomprehensible, look around for one that suits you better!
Next week, we will talk about more ideas for giving an AI desirable values. To prepare, read “Morality models” and “Do what I mean” from Chapter 13. The discussion will go live at 6pm Pacific time next Monday 23 February. Sign up to be notified here.
