What actually happens is that the process control version uses that predictability to dial down the average quality while keeping the product just above total failure level.
AI takes this a step further: it allows cost cutting by replacing human processes with nondeterministic uncontrolled statistical processes. Some percentage of AI users will just be given a dud experience. For which they will, not unreasonably, blame the AI.
So AI becomes a negative quality signal. I've already observed "uses AI generated images" being interpreted as "product is obviously fake and/or bad".
(consumers are very much complicit in this by always choosing the cheaper option - but see Akerloff "Market for Lemons", that may be economically rational if you can't properly distinguish quality!)
