Slight unintended consequence is it creates a significant incentive for politicians to allow their expenses to be picked up by someone else. There are rules in many democracies where "gifts," over small amounts (~$50) must be reported to ethics commissions and scrutinized for opportunity by the opposition, media, and by extension, the public.
In a simple risk game of likelihood vs. consequences, expensing a meal in an upper end restaurant will %90 draw political consequences from an AI, with a high degree of uncertainty in the cost to fight it, vs. accepting the hosts generosity, with a sub-%5 chance of consequences occurring like having to pay your share, or a minor sanction some years into the future.
I'd argue most politicians necessarily make risk and cost/benefit calculations before ethical signalling ones, and the indiscriminate application of rules in this case creates inverted incentives that demoralize the situation, and will cause them to start accepting insignificant bribes.
The economic value of "AI" is mostly to obfuscate and symbolically defray the chain of individual human accountability. While this may be working for the "good guys," in the public interest, it's really about protecting the people who are using what is essentially a Bayesian black box as an ethical proxy for their personal interest. It's fascinating and cool, but it's also a bit disingenuous to accept magical pretexts and other ethical proxies because we perceive them to be "on our side."
