Just a little idea:

In one advertising I saw interesting pyramid with these levels (from top to bottom): vision -> mission -> goals -> strategy -> tactics -> daily planning.

I think if we like to analyse cooperation between SAI and humanity then we need interdisciplinary (philosophy, psychology, mathematics, computer science, ...) work on (vision -> mision -> goals) part. (if humanity will define vision, mission and SAI will derive goals then it could be good)

I am afraid that humanity has not properly defined/analysed nor vision nor mission. And more groups and individuals has more contradictory vision, mission and goals.

One big problem with SAI is not SAI but that we will have BIG POWER and we still dont know what we really want. (and what we really want to want)

Bostrom's book seems to have paradigm that goal is something on top, rigid and stable. Could not be dynamic and flexible like vision. Probably it could be true that one stupidly defined goal (paperclipper) could be unchangeable and ultimate. But we probably have more possibilities to define SAI's personality.
