If even the DoD cannot implement stronger security against the forces of incumbency, it's time to forget it. The holding pattern will continue forever.
Then we can finally say that existing revenue streams, customer relationships and political connections trump technological innovation and efficiency. Sad, but this may be the name of the game.
Certainly hard to argue sensibly that the obstacles don't matter. Even a failed sort of incumbency is almost impossible to dislodge.
