I was really dismayed when MS came up with Metro/Modern and suddenly most vocal designers flipped switch and started to produce designs inspired by the new MS's design language. No creativity there at all, just plain boring simplistic uniformly colored boxes.
I guess even Apple caught the metroitis with iOS 7. No idea what went on over there, from UI that was appreciated as the most beautiful, polished and envied it just borrowed approach from the most controversial that many find disgusting (hey, was the default color palette chosen by color blind people?).
We had the same problem when hiring designers for our creative product - most designers just flat out copied all sorts of ugly trendy flat designs. I really don't want my app to look like it was designed by the 5-year old Miró that just discovered boxes in MS Paint.
What is happening in design? Is it the same thing that happened with classical music when modernists completely broke historic standards and started to produce "intellectual" music that maybe 5% of population can appreciate, the rest just suffers through?
I can automate creation of ugly boxes/flat stuff myself, I don't need designers to do that. From a designer I would expect something original, expression of craftmanship that will discern my work from the others. Not uniformity.
