We may be able to get good AIs to fight the bad AIs? I guess in this case something that pops up saying maybe call the grandson back?
It seems much easier to build an AI that helps less bright people to scam others than one that helps them to not get scammed. One needs to provide clear instructions for a single good scam when explicitly asked to do so, the other would need to provide good defenses to any number of scams and be more or less self-activated. There's also the matter of risks entailed by having large swathes of the population increasing…
Yeah for voice calls nothing yet though the likes of Google/Apple could probably do something. Against your point that bad AI is easier, you have that Google/Apple have more resources than the scammers.
