Michigan Sen. Gary Peters said at an Axios event today that he's worried increased automation due to growth in machine learning will gut the middle class:

"Now I’m not one of these folks who think that all the jobs are going to disappear and we won’t have work," Peters said. “However, I am concerned that if you have a hollowing out of the middle class you may have just two types of jobs.”

Why it matters: Peters, the author of draft legislation meant to address the rise of self-driving cars, is at the frontline of this debate. But Congress has yet to act on renewed concerns about automation and job loss.
