Methinks that is still a lack of understanding, or a disagreement on utility calculations. I myself would rate the universes where I die as lower utility still than those were I get injured (indeed the lowest possible utility).
Better still if in all the universes I don't die.
I do think 'a disagreement on utility calculations' may indeed be a big part of it. Are you a total utilitarian? I'm not. A big part of that comes from the fact that I don't consider two copies of myself to be intrinsically more valuable than one - perhaps instrumentally valuable, if those copies can interact, sync their experiences and cooperate, but that's another matter. With experience-syncing, I am mostly indifferent to the number of copies of myself to exist (leaving aside potential instrumental benefits), but without it I evaluate decreasing utility...
A friend of mine is about to launch himself heavily into the realm of AI programming. The details of his approach aren't important; probabilities dictate that he is unlikely to score a major success. He's asked me for advice, however, on how to design a safe(r) AI. I've been pointing him in the right directions and sending him links to useful posts on this blog and the SIAI.
Do people here have any recommendations they'd like me to pass on? Hopefully, these may form the basis of a condensed 'warning pack' for other AI makers.
Addendum: Advice along the lines of "don't do it" is vital and good, but unlikely to be followed. Coding will nearly certainly happen; is there any way of making it less genocidally risky?
