[Mass Effect] Why do the Reapers consider the Turians to be 'too primitive'?

So in Mass Effect 2 we can hear Harbinger comment on the various species (I believe depending on who is in your party), making remarks on how the non-humans are inferior candidates for a Sovereign-class Reaper.  With regards to the Turians, Harbinger simply states that they "were considered...too primitive."  

I can't really figure out what it means by this.  The Turians are one of the Council races, with the largest military in the galaxy.  They are highly advanced and influential.  So how can they be too primitive?

They have an extremely war-oriented society, to the point that they even export all of their own economics to the Volus, their science and development to the Salarians, and don't even seem to bother with art or aesthetics. They are barely better than the Krogan, and have probably only avoided a similar fate due to the extreme societal value they place on rules, regulations, and hierarchy. Why do you think pretty much every Turian you meet seems angry, frustrated, or has an otherwise itchy trigger finger? They are a species that lives for fighting yet binds themselves in bureaucracy because its more "civilized". Notice that when the gloves come off they can be some of the downright nastiest people you'll meet, like how they handled the Krogan Rebellions and the Human First Contact War. This doesn't mean they are bad people, just that they have foregone natural societal evolution in favor of placing themselves in a system where they can sate their appetite for war while still pretending to be the civilized "good guys". Even Garrus, who is one of the nicest guys you meet, still runs around killing people and playing cowboy for kicks once he steps outside of traditional Turian society and expectation.

Trust me, the Turians would have bombed themselves into the Stone Age a thousand years ago out of boredom if they didn't have the Asari to boss them around and the Krogans, Batarians, and Humans to keep them occupied. They are species completely at odds with themselves, as seen with Garrus.
