@mos_8502 the vibe-coder answer to that is, "I don't need to understand it, I just ask Claude to maintain it, too." And...I scoffed at that idea in the past. But, it's gotten really good.
I think it's still very dangerous in the hands of non-technical folks. And, I think most of the models are still flailing a lot (the frontier models are all pretty good, but Opus 4.5 is the one that Just Works, but all the lower end models are stupid a lot).
I dunno. The ground shifted beneath my feet.
