But the endgame is not here and will likely never be, because unlike ASM, LLMs are not deterministic. So what happens when you need to find the bug in the 100,000k LoC you generated in a few weeks that you've never read, and the agent can't help you ? And it happens a lot. I am not doing this myself so I can't comment, but I've heard many vibe coders commenting that a lot of the commits they do is about fixing the slop they outputted a week prior.

Personally, I keep trying OpenCode + Opus 4.6 and I don't find it that good. I mean it does an OK job, but the code is definitely less quality and at the moment I care too much about my codebase to let it grow into slop.
