Scarlett Johansson's AI row has echoes of Silicon Valley's bad old days

So far, the AI giants have largely played ball on paper. At the world's first AI Safety Summit six months ago, a bunch of tech bosses signed a voluntary pledge to create responsible, safe products that would maximise the benefits of AI technology and minimise its risks. Those risks, originally identified by the event organisers, were the proper stuff of nightmares. Six months later, when the summit reconvened, the word "safety" had been removed entirely from the conference title. Last week, a draft UK government report from a group of 30 independent experts concluded that there was "no evidence yet" that AI could generate a biological weapon or carry out a sophisticated cyber attack.
