At the Milken Institute's Global Conference in Beverly Hills, California, at least four panels so far have focused on technology taking over markets to mining - and most importantly, jobs.

"Most of the benefits we see from automation is about higher quality and fewer errors, but in many cases it does reduce labor," Michael Chui, a partner at the McKinsey Global Institute, said on Tuesday during a panel on "Is Any Job Truly Safe?"

The four-day annual conference, which began on Sunday, has 3,500 invite-only participants exploring "The Future of Human Kind."

Technology has not only done away with low-wage, low-skill jobs, some of the more than 700 speakers said. They cited robots operating trucks in some Australian mines; corporate litigation software replacing employees with advanced degrees who used to sift through thousands of documents prior to trials; and on Wall Street, the automation of jobs previously done by bankers with MBAs or PhDs.

"Anyone whose job is moving data from one spreadsheet to another ..., that's what is going to get automated," said Daniel Nadler, chief executive of Kensho, a financial services analytics company partly owned by Goldman Sachs Group Inc .
