Will artificial intelligence overtake humans in the workplace?

Earlier this year, there were reports on advances in artificial intelligence. Stephen Hawking, Elon Musk and others voiced their concerns about computers overtaking humans, and it could start in the workplace, CBS News' Anthony Mason reports.

"Eventually I think most jobs will be replaced, like 75 percent, 80 percent of people are probably not going to work for a living," New York University's Gary Marcus told Mason earlier this year.

Since that conversation, the jobs issue has attracted more attention. Recently, two books from technology experts in Silicon Valley foretell a potentially jobless future.

Jerry Kaplan is author of the just-released "Humans Need Not Apply: A Guide to Wealth and Work in the Age of Artificial Intelligence."

"The new coming wave of automation is blind to the color of your collar," Kaplan said.

Kaplan said that in the next decade or two, driverless cars could put many of the more than three million licensed professional drivers around the country out of work. While automation long ago revolutionized the assembly line, advances in big data computing power could soon downsize the traditional white collar workforce as well.

"Even what you think of as advanced professions that require a great deal of specialization and expertise, the vast majority of the work is routine, and it's those routine tasks which can be now taken over by computers, so that what used to take the work of 20 lawyers may be done by five lawyers, or 20 doctors may be done by five doctors," Kaplan said.

Maybe even journalists. Now computers are creeping into the reporting field. At The Associated Press, approximately 4,000 corporate earning stories are being written by computers.

"Well, at one time, like when I first got to the AP, we were writing as many as 1,000 earning stories a quarter," AP assistant business editor Philana Patterson said. "I think everybody knows the media industry has been contracting and we don't have as many people working in the newsroom. We eventually got that down to about 300 earning stories a quarter. So we were offering our customers less, and with automation we were able to actually bring those numbers up above what we were doing before."

The AP uses a program called Wordsmith, created by Automated Insights, a company in Durham, North Carolina.

"We can generate millions of stories in a matter of minutes or hours," Automated Insights CEO Robbie Allen said.

Wordsmith takes raw data, like a player's production for Yahoo's fantasy football league, and turns it into weekly recap stories that sound like they were written by a human. But Allen downplays the doomsday scenario.

"I believe that our future is going to be much more of a humans and software working together, and to our knowledge nobody's ever lost a job due to an implementation of Wordsmith," Allen said. "In fact, most of the time we're implementing things that previously didn't exist before."

"We haven't eliminated any jobs, and what it's really done for us is it's allowed us to give reporters and editors time to do more meaningful work," said Patterson.

If computers continue to infringe on humans' territory, what would a mostly jobless population look like?

Marcus said it could lead to dramatic changes.

"I think eventually we're going to move to a society that works on different principles, where the state supports people, maybe from taxes that come from the people that own most robots," said Marcus. "They're going to have a different kind of- almost like a leisure kind of life, but I think more people have come to realize that a guaranteed minimum income from the state really is the endgame here."
