Robot judges will replace humans in the courtroom 'in 50 years'

Robots that analyse a defendant's body language to determine signs of guilt will replace judges by the year 2070, according to an artificial intelligence expert. Writer and speaker on AI Terence Mauri believes the machines will be able to detect physical and psychological signs of dishonesty with 99.9 per cent accuracy. He claims they will be polite, speak every known language fluently and will be able to detect signs of lying that couldn't be detected by a human. Robot judges will have cameras that capture and identify irregular speech patterns, unusually high increases in body temperature and hand and eye movements.
