AI enables more mistakes to be made faster and more convincingly. You have more stuff being generated which means more of it (by absolute quantity) is probably wrong. You have less time to review it because there is more material. Of course everything the wrong stuff included can have analysis making an argument for it attached (courtesy of an LLM). And finally people writ large tend to treat computer output as infalliable.
This increases not just the risk of war crimes and general moral bankruptcy but also of escalation (see the recent Chinese ship close call or the older, and not AI related, bombing of the Chinese embassy in Belgrade due to faulty intelligence) Also dropping multi million dollar missiles on non legitimate targets is a giant waste of money and more human analysis is likely cheaper.
