I've always said that a pilot with a good sense of self preservation was a bonus to his/her passengers.
Now show me a robot that gives a damn.
FADECs, like most automation, are designed by humans and only capable of handling scenarios they have been designed to handle. As a fuel metering system they are brilliant, but not without there limitations - just ask anyone flying a twin engined helo and how they are taught to deal with identifying the failed engine - it's not quite as obvious as you would think.
