Re: blameless postmortems, i think the primary reason for blamelessness is because if you have blameful postmortems, they will rapidly transform (at least in perception) into punishments, and consequently will not often occur except when management is really cheesed off at someone. This was how the postmortem system ended up at Amazon while i was there.
Blameful postmortems also result in workers who are very motivated to hide issues they have caused, which is obviously unproductive.
I’m not sure whether the unspoken context of this comment is “We tried to hire Terry Tao and he declined, citing lack of interest in AI alignment” vs “we assume, based on not having been contacted by Terry Tao, that he is not interested in AI alignment.”
If the latter: the implicit assumption seems to be that if Terry Tao would find AI alignment to be an interesting project, we should strongly expect him to both know about it and have approached MIRI regarding it, neither which seems particularly likely given the low public profile of both AI alignment in general and MIRI in particular.
If the former: bummer.
