Just impossible, ultimately all programming languages boils down to processor instructions which in turn boils down to electronic circuits. The you have to break the laws of physics for something to like that to happen.However, if AI did something contradictory to it's programming then that would be truly worrying.
No computer program no matter how sophisticated can do things it isn't written to do. Doesn't mean when your working on a million lines of code like i have it doesn't do unforseen things and isn't full of loads of contradictions.
