"Wanting X" means "choosing among actions by using your world-model to
evaluate probable consequences and then outputting whichever action
seems most likely to yield consequences with the best fit to X".
Of course this is merely a rough paraphrase of the standard expected
An expected paperclip maximizer "wants paperclips" in the sense of
outputting whichever action leads to the greatest expectation of
paperclips according to the consequence-extrapolator of its world-model.
An expected paperclip maximizer will not knowingly rewrite the part of
itself that counts paperclips to count something else instead, because
this action would lead to fewer expected paperclips, and the internal
dynamics that output actions output whichever action most probably leads
to the most expected paperclips. It may help to think of this
optimization process as a "chooser of paperclip-maximizing actions",
rather than using various intuitive terms which would shift the
conversation from engineering to psychology.
