Maybe one of the most basic applications would be persistent infiltration of niche social organizations, such as radical groups, subversive organizations, etc. Get a profile set up, establish a presence, develop a track record with some credibility. Become an inroad for future interactions.

Rather than devoting a lot of agents to monitoring and working their way into groups, set up an AI to do it. Monitor what's going on and notify the agency if certain triggers are met. At that point a human could take over and begin the investigative process.

AI can be involved in tens of thousands of groups and always be engaged and responsive whereas an agent could not.

Also the ability to digest massive amounts of information and extract understanding from it, rather than looking for key phrases or keywords, then produce summaries of what the information relates to.

Imagine an algorithm that searches for keywords like "bomb" and then flags a conversation for review by an agent. That agent then needs to look at context and tangential information, go back and search profiles for previous posts and begin to try and put together a picture of what's going on, taking days or weeks to do so. An AI could do that for thousands of instances simultaneously.

Is any of this "concerning"? I guess I leave that up to the individual to decide for themselves.
