Yep. There's also been a relentless push for the past two decades or so to standardize many aspects of software development:

* programming languages (JS)

* frameworks (React)

* open source libraries

* platforms (Web, mostly)

* design systems (shadcn for newer apps)

Guess what makes it easier for automation to come in?

Our need for it to be easy and standard contributed to the success of LLM use in software engineering. I suspect it would have done well without some of those factors, but it may have taken longer.
