Even if they were to make some actual progress, most of it would probably be regarded too dangerous to be released. Therefore I predict that you won't see much more of it ever.

That seems unlikely - well, the being too dangerous, not sure about the regarding. The philosophy of digitizing human preferences seems particularly releasable to me, but depending on how you break the causes of unFAI into malice/stupidity, it can be a good idea to release pretty much anything that's easier to apply to FAI than to unFAI.
