OK, my title is somewhat premature, but the end is nigh!

DRY = Don't Repeat Yourself

was a fundamental rule when I learned to code[^1] and has now become a popular stalking horse[^2]

As of several years ago, the DRY principle was almost dead due to:

  • IDEs with powerful refactoring tools, such as LSPs
  • strongly typed languages which allow for safe "quantum" edits where the compiler can identify very distant dependencies anywhere in the codebase
  • software startup economics, that is, an imperative to ship as fast as possible, while taking on the right kinds of technical debt
  • lots of abuse, e.g., for "coincidental repetition", inappropriate coupling, and premature optimization

With AI-assisted tab completion[^3], tons of repetition and boilerplate empowers programmers to be more productive rather than less.

With LLM coding:

  • quantity of boilerplate leads to more adoption[^4]

  • quantity of lines of code produced leads to more easily measured metrics, and

  • cognitive cost of boilerplate gets...
