I blame Henry Ford and his dispute with Robertson (the square drive
bit guy) causing him to choose Phillips screws.


Actually the Phillips screw was deigned to cam out to avoid bit and screw
breakage. The Robertson torx and some other screws are designed not to cam
out. Breaking is no longer a problem because of the clutching now available
on modern assembly tools.
