Pretty sure those would be better at social engineering than the web dev personality… except that you have to build in a betrayer layer into the personality, so it's running that stuff but also serving a hidden agenda.
You'd be basically trying to build an AI spy, a betrayer that's engaging with actual people but has an agenda (for instance, 'everybody I befriend needs to eventually be signed up to sell Amway') and humans do have experience with this sort of thing. The difference is scale: there'll be a LOT of models out there interacting with people and trying to be acknowledged as people… or as innocuous models that don't have an hidden agenda.
In other words, scams are going to massively increase in success rate ... and what are banks (for example) supposed to do? Other than SCREAM to governments for outlawing AI and trying to force responsibility on anyone else?
