Tech could lose its social acceptance unless it makes people’s lives better – and trade unions want an urgent conversation

“Who wouldn’t want a robot to watch over your kids?” Elon Musk asked Davos delegates last week, as he looked forward with enthusiasm to a world with “more robots than people”.

Not me, thanks: children need the human connection – the love – that gives life meaning.

As he works towards launching SpaceX on to the stock market, in perhaps the biggest ever such share sale, the world’s richest man has every incentive to talk big.

Yet as Musk waxed eccentrically about this robotic utopia, it was a reminder that major decisions about the direction of technological progress are being taken by a small number of very powerful men – and they are mainly men.
