Can AI griefbots help us cope with death?

If someone you loved died, would you want to keep chatting to them? Now you can - with an AI griefbot. The idea is you use their texts, emails and voice notes, as well as photos and videos, to train AI to reply in the dead person’s tone and style. It can be through text-based conversation or even an AI-generated voice.

The "digital afterlife" industry is now worth more than $130 billion. Is this just the latest way for humans to try to maintain a relationship with their deceased loved ones? Or could it negatively affect the grieving process, if people start to believe that person is actually still alive through the technology? And what might companies do with all the data we input?

Tech journalist Tamzin Kraftman explains this growing area of tech and the pros and cons of using griefbots. Andy Langford, clinical director at Cruse, a bereavement charity in the UK, gives us his thoughts. And we hear from Muhammad Ahmad in the US, who developed his own grief bot of his dad.
