Like many other grandmothers, Daisy likes to knit, and she isn't very good with technology. Or, at least, that's what she might tell people on the phone. Daisy also describes herself as "your worst nightmare." But don't worry, she's not talking to you — she's talking to phone scammers. That's because Daisy is actually an AI chatbot. She was created by UK phone company Virgin Media O2 to speak to scammers on the phone and make them believe they're talking to a real person. Older people are very vulnerable to scams. In July, a UK study found that about 67% of people over the age of 75 were victims of at least one scam attempt in the six months before the study — with almost 75% being phone scams. Enter Daisy, who has been trained to have conversations with phone scammers and waste their time. Virgin Media O2 worked with Jim Browning, a YouTuber who has spent years "scambaiting" — that is, pretending to be a clueless victim to waste scammers' time. And that's the whole point — Daisy can't stop scammers, but she can slow them down. "Whenever she's on the phone with a scammer, your parents, your grandparents, your relatives, are not being scammed," Browning told Sky News. The company says Daisy is already "wasting hundreds and hundreds of hours of scammers' time," and has shared real-life conversations the chatbot has had with scammers. Some conversations last nearly an hour. She talks about her cat, Fluffy, and people in her family. In some conversations, she gives the scammers what they want — bank details. But of course, they're not real. Murray Mackenzie from Virgin Media O2 said Daisy is also a reminder that the person you're speaking to on the phone might not always be who they say they are.
