Billionaire Bill Gates on the impact of A.I.: 'Certainly' we can look forward to longer vacations

There have been some dour predictions about the potential of artificial intelligence from some high-profile technologists. For example, billionaire tech entrepreneur Elon Musk has said AI will be more dangerous than North Korea. Legendary physicist Stephen Hawking says that AI has the potential to be the "worst event in the history of our civilization." But billionaire Microsoft co-founder Bill Gates has added a bit of levity to the conversation. Gates says AI will mean longer vacations.
