I had conceived of something like the Turing test but for intelligence period, not just general intelligence.

I wonder if general intelligence is about the domains under which a control system can perform.

I also wonder whether "minds" is a too limiting criteria for the goals of FAI.

Perhaps the goal could be stated as a IUCS. However, we dont know how to build ICUS. So perhaps we can build a control system whose reference point is IUCS. But we don't know that so we build a control system whose reference point is a control system whose reference point . . . until we get to some that we can build. Then we press start.

Maybe this is a more general formulation?
