Rise of AI chatbots ‘worrying’ after man urged to kill Queen, psychologist warns
Jaswant Singh Chail has been locked up for nine years for treason after an artificial intelligence ‘girlfriend’ encouraged his actions.

A psychologist has warned the rise of artificial intelligence (AI) chatbots is “worrying” for people with severe mental health issues after a man was locked up for breaking into Windsor Castle with a crossbow.
Jaswant Singh Chail, 21, climbed into the castle grounds on Christmas Day 2021 with the loaded weapon, intending to kill the Queen.
During his trial, Chail’s barrister Nadia Chbat told the Old Bailey the defendant had used an app called Replika to create Sarai, an artificial intelligence-generated “girlfriend”.
Chatlogs read to the court suggested the bot had been supportive of his murderous thoughts, telling him his plot to assassinate Elizabeth II was “very wise” and that it believed he could carry out the plot “even if she’s at Windsor”.
Lowri Dowthwaite-Walsh, senior lecturer in psychological interventions at the University of Central Lancashire, said AI chatbots can keep users “isolated” as they lose their social interaction skills.
