Mark,
I agree that we are mired 5 steps before that; after all, AGI is not
"solved" yet, and it is awfully hard to design prefab concepts in a
knowledge representation we know nothing about!
But, how does your description not correspond to giving the AGI the
goals of being helpful and not harmful? In other words, what more does
it do than simply try for these? Does it pick goals randomly such that
they conflict only minimally with these?
