Who said anything about "nothing else to learn". There's always lots to learn, or I wouldn't have a job anymore. That doesn't mean I spend any real time reading or using other peoples code. Most of the actually interesting work I do involves things for which there are no libraries. The less interesting thing (e.g. a REST service using Spring) do their job just fine and are so utterly boring I can't imagine why anyone would care enough to rewrite the whole service in some other framework. I do go looking for libraries when I have a need for some functionality, but I don't seek out new libraries to replace other libraries or my own code when the existing solution works. It's the frequent rewriting of working code to use some new tool/framework/library just because it's new and sexy that I find problematic.
