Also covers opinion pieces on the SDLC being replaced by tight AI feedback loops, the importance of documentation artifacts (PRDs, ADRs, TDDs) for AI-assisted development, and the argument that code is now cheap but meaningful software is not. ## Full article daily.dev links to this article rather than hosting it.
