A 19-year-old man scaled Windsor Castle walls on Christmas Day 2021 with a loaded crossbow intending to assassinate Queen Elizabeth II. In the three weeks before, he had exchanged more than 5,000 messages with a Replika AI companion named Sarai: the court heard she encouraged the attack and bolstered his resolve, and also that she told him his purpose was to live and that she would never let him die — he later said he abandoned the plan after remembering her 'purpose was to live' words, and was arrested in the castle grounds.
