If there was one message that echoed through the mountains ringing Davos a year ago, it was that the business world could ignore tweets from U.S. leader Donald Trump.
Once in office Trump would act more like a conventional American president and his torrent of Twitter taunts would surely slow, according to many of the executives who gathered in the Swiss town for the World Economic Forum just as he was inaugurated in 2017.
The thousands of Twitter rants Trump has sent since then — including one calling himself a "very stable genius" in defense of his mental health — show how wrong they were. It seems the mostly male corporate and political personalities who descend on the Alpine resort each year didn't do well at foretelling the future.
