I don't agree. By using enough force, by exponentially analyzing
every aspect of a completely subordinate computation, total submission
can be achieved, even if it means simply stopping the subordinate
computation, or deferring it arbitrarily long.

Thanks for that. I had often supposed that determining just what
your client is doing might be intractable, and your Rice's Theorem
seems to confirm that.

Well, yes, but it would still be easy to be proactive about it,
supposing one were ruthless enough.

Your conditions seem to amount to
(1) determine what is the sentient's equivalent of the fronto-orbital
(2) determine the set of (hopefully simple) rules or general laws
(3) verify that all computation under this entity's control is also
under the control of these predispositions
I might suppose that any one of these three might be intractable, or worse.
(Intuitively, we seem to be running up against the problem of "central
control", the most awful unconscious premise of 20th century thinking.)
Moreover, the Extropian principle of continual self-transformation, if
allowed in the dominated subjects, would require continual re-evaluation.
Perhaps Eliezer will succeed in the much more modest project of enabling
(or evolving) the FAI to keep *itself* from going off the rails, but as
for keeping everyone else from doing X---to the degree that it makes sense
to suppose computation exists outside the SI itself---that's much harder.
