Artificial intelligence adoption could lead to significant job struggles for entry-level workers as companies boost productivity, according to ServiceNow CEO Bill McDermott. McDermott told "Squawk on the Street" on Friday that unemployment for new college graduates "could easily go into the mid-30s in the next couple of years." "So much of the work is going to be done by agents. So it's going to be challenging for young people to differentiate themselves in the corporate environment," he added.
