A few examples of technology that moved 'forward' but decreased productivity for those who moved with it from my 'lived' experience:

1) CASE tools (and UML driven development)

2) Wizard driven code.

3) Distributed objects

4) Microservices

These all really were the hot thing with massive pressure to adopt them just like now. The Microsoft demos of Access wizards generating a complete solution for your business had that same wow feeling as LLM code. That's not to say that LLM code won't succeed but it is to say that this statement is definitely false:

> Technology moves forward and productivity improves for those that move with it.
