> I just finished writing a post about exactly this. Software development, as the act of manually producing code, is dying.

It was never that. Take any textbook on software engineering and the focus was never the code, but on systems design and correctness. I'm looking at the table of contents of one (Software Engineering by David C. Kung) and these are a few sample chapters:

  ...
  4. Software Requirement Elicitation
  5. Domain Modelling
  6. Architectural Design
  ...  
  8. Actor-System Interaction Modeling
  9. Object Interaction Modeling
  ...
  15. Modeling and Design of Rule-Based Systems
  ...
  19. Software Quality Assurance
  ...
  24. Software Security

What you're talking about was coding, which has never been the bottleneck other than for beginners in some programming languages.
