If you look at how the job market has changed over the years, you know that technology has made some of what we do obsolete. One inventor and business magnate thinks there will be more of that change coming.

Bill Gates told the American Enterprise Institute machines could continue to take jobs away from humans.

“Technology over time will reduce demand for jobs, particularly at the lower end of the skill set,” Gates explained. “Twenty years from now labor demand will be lowered, and I don’t think people have that in their mental model.”

Gates calls it ‘software substitution,’ and Rice University's Chris Bronk says it's not just talk.

“I think Gates is right. The combination of software and robotics could change the job picture in the United States, and not in a good way,” Bronk told KTRH.

And he says it’s something that’s been happening for a while.

“The travel agent was special twenty years ago because they had connections. Now we have complete transparency into airline routes, where they go and how much tickets cost,” Bronk explained.

So are we ready to deal with more change? Bronk isn’t so sure.

Bronk said, “That’s the question. If computers are filling so many jobs how do we derive value as human beings? I think you will see a lot of societal impacts that we would not have imagined.”

While Bronk thinks many of you should be nervous, jobs that require the human touch; nursing for instance, won't wind up being affected.
