I currently do not wish to be wireheaded, but I'm uncertain whether that aversion will turn out to be coherent. A technique for preventing AIs from wireheading has not yet been discovered, and there is no proof that one exists. So in that sense LW's thoughts on the subject are necessarily incomplete.

I also don't feel that the least convenient wireheading machine has really been dealt with, that I can recall. Say a machine can really, genuinely convince me that I'm getting all the things that I want and I'm not aware I'm being deceived, so much so that I can't distinguish the real world and the machine, even in principle. I don't know what it would mean for me to say that I didn't prefer that world. What are my preferences about, at that point?
