It is simplest to just say that it is obsolete. It has largely been obsoleted by CEV. But SIAI’s thinking on Friendly AI is fluid/dynamic and does not accord with any dogma or single published paper. You can say that it clusters around “CEV-like ideas”. (There is a general consensus that some sort of extrapolation is a good idea rather than directly implementing literal human wishes.) For an example of more recent thinking, see Muehlhauser & Helm’s draft paper on the SIAI blog.
