This is not attacking the people on the phone, it's attacking the whole operation. The person on the phone is going to be on the phone regardless of whether they're talking to an AI or a victim. The AI is merely talking on the phone, not abusing the caller in any way (other than perhaps eating into their commission).

I also think it's extremely simplistic to call the people making the calls "slaves". A lot of the time, they are in facr the perpetrators. Even when they are part of a more organized operation, they (1) are likely paid per successful scam, so they are co-interested in hurting you, and (2) fully aware they are scaring and stealing from someone.

So I wouldn't call these people slaves, I'd call them low-level criminals.
