Could you be a little clearer on what the “obvious moral and ethical issues” are? Personally I’m not sure what you’re referencing, and I also don’t think the many of the moral and ethical issues are obvious. If they were, then I suspect countries like the UK wouldn’t already be trialing many of these technologies.
AI today is on a level of an illiterate toddler with a talent for stochastic at least. Using it to classify people is unethical because it puts suspicion on them without evidence or sense.
