It’s really an editor problem. Theoretically there could be a world where all code is in one file, and that’s ok because the editor allows you to effortlessly navigate your code via a variety of means. For some this might be using a keyboard, for others more visually inclined, perhaps in Java there is a browsable visual model. I’m honestly surprised there doesn’t have exist an editor/language that abstracts away the concept of source code files completely. I assume that there is a good chance that in 50 years time we won’t be coding using collections of text files.
