Amazon's new concept convenience store doesn't just save money, it saves shoppers' time. That, however, is part of what makes the rise of the robots unstoppable, one expert said. At a time when a growing number of observers have lamented the potential impact of growing automation on flesh and bone workers, the retail giant introduced something that may be a game-changer. On Monday, Amazon announced a new Seattle location, Amazon Go, that has no registers. Instead, shoppers scan into the store with their free Amazon Go app, shop as normal, and leave the store with the items billed to their Amazon.com account. "With Amazon, it's not just about reducing labor costs at all — they've come up with something disruptive," Martin Ford told CNBC's "Power Lunch" this week. "I don't think there is anyone that doesn't hate standing in line at a retail store, and they've figured out a way to basically get rid of those lines," he said. "So this is something that is not just about eliminating jobs, it's going to create enormous advantages for consumers. So it's an inevitable process."

It's unclear exactly how ambitious Amazon's expansion plans are for Amazon Go, but it faced immediate backlash as "the end of jobs." "I don't think we can stop it," said Ford, the author of "Rise of the Robots: Technology and the Threat of a Jobless Future." "It's a part of capitalism, that there's going to be this continuous drive for more efficiency."

Ford pointed out that retail salespersons and cashiers were among the occupations with highest employment in the U.S., according to Bureau of Labor statistics data from earlier this year.

What it leads to is more job destruction, and less job creation, especially for average typical people that don't necessarily have PhDs from MIT. Martin Ford Author of "Rise of the Robots: Technology and the Threat of a Jobless Future."
