The new robot revolution will take the boss's job, not the gardener's

Guy Ryder is an old hand at Davos. The director general of the International Labour Organisation has seen it all: the years when the global business elite is brimful of confidence and the years, such as 2017, when the top 1% of the top 1% is fretful. Ryder detected parallels with 2009, when the global economy seemed to be heading for a second Great Depression. Eight years ago, the attendees were shaken by the banking collapse but showed little contrition. This year, they were alarmed by the populist anger that was evident in Brexit and Donald Trump's arrival in the White House but couldn't really understand why it was happening.
