It was my understanding that all AI technology/approaches need some sort of training. And that this training required some sort of human intervention to grade "correctness" In companies that I have worked for that want to use AI; they always have a clause in the privacy agreement allowing employees to look at users' content in order to determine how well the algorithm was doing. There are some differences: 1. PII was redacted (to the extent possible); 2. Customer could opt-out.; 3. the AI wasn't core to the service. That said - sci-fi AI does seem to require humans behind the curtain. Personally, I am more comfortable with a human being my virtual "AI" assistant than I am with real AI. I feel a human is less likely to make a mistake that will cause me personal damage, there is more responsibility/liability to doing a good job.
