The first time I saw something like this in action was in a video about agentic blabla features in VS Code on the official VS Code YouTube channel. Pretty much write a complete and detailed specification, fire away and hope for the best. The workflow kinda clicked for me then but I still find a hard time adjusting to this potential new reality where slowly it won't make sense to generally write code "by hand" and only intervene to make pinpoint changes after reviewing a lot of code.

I've been reading a book about the history of math and at some points in the beginning the author pointed out how some fields undergo a radical change within due to some discovery (e.g. quantum theory in physics) and the practitioners in that field inevitably go through this transformation where the generations before and after can't really relate to each other anymore. I'm paraphrasing quite a bit though so I'll just recommend people check out the book if they're interested: The History of Mathematics by Jacqueline Stedall

And the aforementioned VS Code video, if I remember correctly: https://youtu.be/dutyOc_cAEU?si=ulK3MaYN7_CPO76k
