No way. What Master of Defenestration said, but also because sometimes in an emergency it's better than nothing. There have been times when my brain hasn't been capable of getting the shot any other way. Admittedly my usual emergency mode would be Av (I normally shoot in manual) but very occasionally Green Box mode has been necessary.
In any case, why the assumption that it's necessary to know how your camera works? Just because there are enthusiasts who like to get technical doesn't mean everyone should be forced to, or that it's not possible to get decent photos in auto. My mother has a micro four thirds camera and doesn't know how to shoot in any mode but auto, but she recently won a FIAP gold medal.
Do you think cars should only be made with manual gearshifts?
