"I think it gives time back to people to focus on pursuits that are creative and important," he added. His comments come after U.S. Treasury Secretary Steve Mnuchin said he is not worried about AI replacing jobs for at least 50 to 100 years. "I think that is so far in the future -- in terms of artificial intelligence taking over American jobs -- I think we're, like, so far away from that that," said Mnuchin at an event held by Axios last week. "Not even on my radar screen," he added. The comments were at odds with the technology industry.

Twitter might finally let people fix their bad tweets. The troubled company's CEO, Jack Dorsey, has suggested that he might have the site add an "edit" button so that updates can be fixed after they are posted. It was just one of a range of new year's resolutions that he made after taking requests from its users. Mr Dorsey admitted that the site needs such an edit button, but said also that he will need to think more about how it can be rolled out. The suggestion came after Mr Dorsey sent out a tweet asking users what they would want to see change about the site in 2017. A range of responses followed, including a number of people who asked for tweets to be allowed to be changed once they had been posted.
