>Eliezer:Sometimes changing yourself the wrong way, and being murdered or suspended to disk, and replaced by an earlier backup.

Uh, no. If restoration from backup happens shortly after the wrong change I'd think of it as a day you wasted and don't remember, definitely not a murder. Something only weakly to be avoided.

>Unknown:This actually happens to us all the time, without any modification at all, and we don't care at all, and in fact we tend to be happy about it,

*Most* don't care. I for one am kind of worried about my personal goal drift and what my (natural) future brain neurochemistry changes could do to current values.
