I find it interesting that almost all the beloved AI characters in sci-fi have personalities ranging from 'a little bit snarky' to 'raging asshole'. Given the tendency of media to influence to aesthetics of actual tech products that follow, ten years ago I would have predicted that an AI assistant would be given a personality along the lines of Cortana (Halo) or Jarvis (iron man). But somehow half a dozen companies in fierce competition with each other all decided that the right move was to go with more-sycophantic-c3p0.

I find that it does a decent job at not being a yes man if you specifically ask it to be critical, cut the crap, etc.
