This seems to have the classic 3 wishes from a genie problem. We may
not be intelligent enough to formulate the "wish" clearly enough that
it does not generate quite unintended evil consequences when "granted"
by a sufficiently powerful process/being.

Who/what is dong the construction of U(x)?

Is a sentient being within a simulation any less sentient than any
other? Perhaps you are assuming or which to assume boundaries where
none really exist.

It is a much of a constraint as choosing the fundamental physical
constants of a universe in other words. :-)

The phrase "our collective volition" is worrisome. It is actually from
above your extrapolation from actual human beings of what "our
collective volition" is, correct?

I greatly sympathize. However, explanations beyond potshots clarify
thinking and bring in other viewpoints that may be essential. In
particular the goals of the system should be explained well and with
clarity to the maximal extent possible before solving the technical
problems of their implementation or at least a theory of their
implementation. A lot of the questions are about goal-level
