It was mainly rhetorical; I tend to think that what holds back today’s FAI efforts is lack of rationality and inability of folks to take highly abstract arguments seriously.
Can you clarify what the relevant difference is between including a too-young person in the target for a CEV-extractor, vs. pointing a growth-simulator at the too-young-person and including the resulting simulated person in the target for a CEV-extractor?
Potentially bad things that could happen from implementing the CEV of a two-year-old.
Humans acquire morality as part of their development. Three-year-olds have a different, more selfish morality than older folks. There’s no reason in principle why a three-year-old who was “more the person he wished he was” would necessarily be a moral adult...
CEV does not mean considering the preferences of an agent who is “more moral”. There is no such thing. Morality is not a scalar quantity. I certainly hope the implementation would end up favoring the sort of morals I like enough to calculate the CEV of a three-year-old and get an output similar to that of an adult, but it seems like a bad idea to count on the implementation being that robust.
Consider the following three target-definitions for a superhuman optimizer: a) one patterned on the current preferences of a typical three-year-old b) one patterned on the current preferences of a typical thirty-year old c) one that is actually safe to implement (aka “Friendly”)
I understand you to be saying that the gulf between A and C is enormous, and I quite agree. I have not the foggiest beginnings of a clue how one might go about building a system that reliably gets from A to C and am not at all convinced it’s possible.
I would say that the gulf between B and C is similarly enormous, and I’m equally ignorant of how to build a system that spans it. But this whole discussion (and all discussions of CEV-based FAI) presumes that this gulf is spannable in practice. If we can span the B-C gulf, I take that as strong evidence indicating that we can span the A-C gulf.
Put differently: to talk seriously about implementing an FAI based on the CEV of thirty-year-olds, but at the same time dismiss the idea of doing so based on the CEV of three-year-olds, seems roughly analogous to seriously setting out to build a device that lets me teleport from Boston to Denver without occupying the intervening space, but dismissing the idea of building one that goes from Boston to San Francisco as a laughable fantasy because, as everyone knows, San Francisco is further away than Denver.
That’s why I said I don’t understand what you think the extractor is doing. I can see where, if I had a specific theory of how a teleporter operates, I might confidently say that it can span 2k miles but not 3k miles, arbitrary as that sounds in the absence of such a theory. Similarly, if I had a specific theory of how a CEV-extractor operates, I might confidently say it can work safely on a 30-year-old mind but not a 3-year-old. It’s only in the absence of such a theory that such a claim is arbitrary.
It seems likely to me that the CEV of the 30-year-old would be friendly and the CEV of the three-year-old would not be, but as you say at this point it’s hard to say much for sure.
(nods) That follows from what you’ve said earlier.
I suspect we have very different understandings of how similar the 30-year-old’s desires are to their volition.
Perhaps one way of getting at that difference is thus: how likely do you consider it that the CEV of a 30-year-old would be something that, if expressed in a form that 30-year-old can understand (say, for example, the opportunity to visit a simulated world for a year that is constrained by that CEV), would be relatively unsurprising to that 30-year-old… something that would elicit “Oh, cool, yeah, this is more or less what I had in mind” rather than “Holy Fucking Mother of God what kind of an insane world IS this?!?”?
For my own part, I consider the latter orders of magnitude more likely.

I’m pretty uncertain.
