Tech bosses have been warning that artificial intelligence is a threat to our very existence and will soon take our jobs and outsmart us all.

But it has now turned on a common enemy, creating a cause we can all get behind: winding up scam callers.

Tired after years of being inundated by cold callers, 54-year-old Californian Mr Anderson has taken a stand.

After much trial and error he has perfected a technology using ChatGPT4 that allows users to choose between five different personalities to pick up the phone and speak to scammers on their behalf.

For $24.99 (£19.60) a year, users can choose between Salty Sally, an overworked mother, Whiskey Jack and senior citizen Whitey Whitebeard to take on call centre staff.
