"On the face of it, this sounds like bad news for people," Branson admits (and Elon Musk certainly thinks so). But unemployment rates will be about the same in 20 years, even if the kind of jobs have changed, according to Rob Atkinson, founder and president of the Information Technology and Innovation Foundation writing in the Bureau of Labor Statistics' Monthly Labor Review. And if "governments and businesses are clever, the advance of technology could actually be really positive for people all over the world," says Branson. For example, governments should pay for workers to be retrained, Branson says, and there will need to be a way to keep people's income the same. But with solutions to such issues, more technology could help create "smarter working practices," says Branson. "Could people eventually take three and even four day weekends? I think so," he says.
