We are going from the era of manual, line-by-line mental model transcription to one where software engineers can focus on data structures, software architecture and algorithms. Hadn’t good developers been focussing on those things, and other high-level modelling that relates the software system back to the underlying real world domain, for many years before the LLMs were in the picture? I’d even say that it’s one of the most reliable markers of a more senior/experienced developer that their code reads like a clear and logical explanation of what the system does and why, with concerns well separated and minor details and technicalities abstracted away so they don’t clutter the rest of the code.
