More than 200 prominent individuals and 70 organisations want international agreement on 'do not cross' red lines for artificial intelligence, to prevent risks to humanity. We speak to Stuart Russell, professor of computer science at the University of California in Berkeley, who is backing the call. He spells out some of the potential risks that AI could pose to us all, and says global agreement on AI red lines is the solution.

Also on Tech Life this week: We look at how artificial intelligence is having an impact on the legal profession. In Ghana, holograms are helping to spread breast cancer health advice. And Shiona McCallum speaks to a young tech Youtuber in Dubai.
