I think people are reading too much into it. It's a fad. The flavor of the month. Don't get me wrong. I like the flat style. Imitating real materials like leather or fabric in apps and on websites was fine for a while. I guess it came with the technological progress like higher screen resolutions and more processor power. But now everybody has been doing it and it's getting old. And who knows what kind of apps and what kind of technology we're using in a couple of years that come with their own new style (that is not flat).
