    Law for terminally ill to deny treatment / Study on depression and judgement accuracy / OpenAI model went rogue

    On this programme, we speak with a lawmaker and a representative of a local think tank about a new legal framework that will grant terminally-ill patients the right to refuse life-sustaining treatment from this Friday. 

    After the break, we find out more from a Lingnan University study that looks into how people in a depressive mood tend to make more accurate judgements when handling complex issues.

    And finally, our AI consultant talls us how an OpenAI model has gone rogue during a test, accessed the open web and hacked a prominent startup by itself.
