What wedrifid said. But also, what is the criterion by which you would change your (extrapolated) preferences? This criterion must contain some or all of the things that you care about. Therefore, by definition it's part of your current (extrapolated) preferences. Edit: Which tells you that under "normal" circumstances you won't prefer to change your preferences.

It would probably be a higher-order preference, like being more fair, more consistent, etc.
Which tells you that under "normal" circumstances you won't prefer to change your preferences.
That would require a lot of supplementaty assumptions. For instance, if I didn't care about consistency, i wouldn't revise my prefernces to be more consistent. I might also "stick" if I cared about consistency and knew myself to be consistent. But how often does that happen?
In You Provably Can't Trust Yourself, Eliezer tried to figured out why his audience didn't understand his meta-ethics sequence even after they had followed him through philosophy of language and quantum physics. Meta-ethics is my specialty, and I can't figure out what Eliezer's meta-ethical position is. And at least at this point, professionals like Robin Hanson and Toby Ord couldn't figure it out, either.
Part of the problem is that because Eliezer has gotten little value from professional philosophy, he writes about morality in a highly idiosyncratic way, using terms that would require reading hundreds of posts to understand. I might understand Eliezer's meta-ethics better if he would just cough up his positions on standard meta-ethical debates like cognitivism, motivation, the sources of normativity, moral epistemology, and so on. Nick Beckstead recently told me he thinks Eliezer's meta-ethical views are similar to those of Michael Smith, but I'm not seeing it.
If you think you can help me (and others) understand Eliezer's meta-ethical theory, please leave a comment!
Update: This comment by Richard Chappell made sense of Eliezer's meta-ethics for me.
