Is there any way to help the elderly navigate this shift?
"Ignore anyone asking you for money unless you know them and they do it in-person."
Easier said than done. One of most popular scam here is a scammer using deepfake/ai calling victim saying there was serious accident to one of victim's relative and they need money for hospital (that's how it works here, money for proper caring). The victim would be panic and send the money.
Usually, the scammer will think of a scenario that give the victim very limited time to stop and think, or put them in the state that fear takes over their mind
That is completely impractical for most people.
