The problem with flat design is the human optical perception is the product of literally hundreds of millions of years of evolution, and it is designed for a three dimensional world. Flat design the latest example of a utopianistic drive that started in the 20th century by some intellectuals to make a world that fits robots, not human beings. Other examples are modern classical music and modern architecture. Modern classical music never caught on because it simply doesn't fit the human auditory system. Ditto modern architecture,though it has persisted partly for business reasons, and has been greatly modified to make it more humane.
