I think about these frameworks as products. They are meant to solve specific problem for specific audience. I also think we need to start differentiating between different classes of developers. I think a good analogy is car mechanic vs mechanical engineer. when a car is made there will be a lot of need for mechanical engineering. Once it's on the road and needs to be fixed is when car mechanic comes into play. You need to decide whether you want to be mechanical engineering or a mechanic - skillet is very different.
