I cannot comment about the technology but I sure as hell can at a people level. I was a speaker at a conference where one of the Palantir cofounders gave a keynote. This was a conference organized by college students for their peers. As with all such situations these kids worked incredibly hard and his talk was incredibly disrespectful to that.
If I hadn't been so disgusted I would have thought to record it. Rather than talk about anything relevant to his audience, or frankly anything informative, he told 'stories'. We have all seen that type of talk, but I have never seem one which so blatantly braggadocious about his interactions with this and other country's intelligence branches. I saw it somewhat ironic that for someone who works for Peter Theil the level to which the talk, and his representation of the 'good' the company does was so absolutely and apologetically statist and authoritarian. He talked about who's jet he rode on, who he knew, and other things that seemed simply organized to ensure we knew just how important he was. Several of the stories were overtly misogynistic, and none of them had any useful knowledge about Palintir or working for them. I was sitting with another speaker and we were literally shaking our heads. I felt bad for the organizers and felt the shame he[the speaker] seemed incapable of.
