Work done by Lesswrongians could decrease the workload of such an FAI while providing immediate results. If it takes twenty years for such a thing to be developed, that's twenty years in either direction on the good/bad scale civilization could go. This could be the difference of an entire year that it takes an FAI to implement whatever changes to make society better.

You are not taking AI seriously. Is this intentional?
A superintelligence could likely take over the world in a matter of days, no matter what people thought. (They would think it was great, because the AI could manipulate them better than the best current marketing tactics, even if it couldn't just rewrite their brains with nano.)
It may not do this, for the sake of our comfort, but if anything was urgent, it would be done.
As Multiheaded added, "Personal is Political" stuff like gender relations, etc also may belong here.
