IMVHO the problem lie in "specialization": in the past most technicians of any fields have a certain generic culture and comprehension of the world, these days they are so "specialized" to be unable to see the big picture at CHILDISH levels. As a result no matter the skills, if you do not know the world you working on it's only by chance if you design something good for such world. Developers MUST KNOW the big picture.
