Low trust is not a reason that code can’t be battle tested. All non battle tested code starts as low trust by default. AI written or otherwise. I’m not even sure what you mean by fragmentation tbh. This feels like a very vague argument in general.

But you’re right that it’s the hill climb of human trust that AI is going through right now. Some of us are just farther along than others. Some of us refuse to consider trusting AI out of fear, and not rational evaluation of its capability.
