Yes, this is true as long as the method or function doesn't contain if's changing the behaviour depending on the data. In other words if the problem is so well defined that you can create a method that solves the problem and it doesn't need to take into account x variations of the problem then it is fine. This is the copy-paste versus creating a function discussion. Problem is the x variations of the problem and you need the code to do different things depending on the variation, we usually break the modularity of the function instead of separating the generic and non-generic parts. Hence the ifs in the function. From what I have seen people are unable to do this in their own codebase properly so I don't think it will happen globally. But on the other hand libraries are kind of the answer to the problem and as problems get well defined, one starts using libraries. Raising the level of abstraction is a continuous process.
