I thought wireheading meant stable high pleasure without content rather than an enjoyable simulated world. What do other people think wireheading means?
Well, technically the term "wireheading" comes from experiments which involved inserting an electrode (a "wire") into a rat's pleasure center and giving the rat a pedal to apply electric current to this wire. So yes, in the narrow sense wireheading is just the direct stimulation of the pleasure center.
However I use "wireheading" in the wide sense as well and there it means, essentially, the focus on deriving pleasure from externally caused but internal experiences and the lack of interest in or concern with the outside world. Wireheading in the wide sense is, basically, purified addiction.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
