Davids problem is ?

"It appears that one of the emotion mapping and facial recognition sensors is the root of the problem," Stuart-Rose further explains, "The David 7's apparently misread human emotions such as surprise and interest, interpreting them instead as anger or frustration." this is taken from the official weyland industries press section of their website. So anybody in that prometheus research team that shows interest and surprise old David is going to recognise it as Anger and frustration. wonder what that would make him do then, seeing as being in a new world everyone will be showing interest and surprise, thats a lot of anger and frustration.
