Amazon just opened a store with no checkouts. But users noted a problem

The new, better age is finally here: we can finally go shopping without having to talk to anyone at all.

Amazon Go, the new store with no checkouts in Seattle, relies on cameras and electronic sensors to identify each customer, tracking the items they put in their shopping bags.

When you leave the store, any purchases are billed to your credit cards.

But people have pointed out one big problem with this brave new world.

Amazon is not scrapping all supermarket jobs. The retail giant is hiring some employees to deal with technical issues, stock shelves and ID customers buying alcohol.

But the retail giant's first real-life step towards automated stores is not a good once for the millions who work for US supermarkets.

Some are arguing that a high minimum wage ups costs for supermarkets, so they are more likely to cut jobs and resort to automation.

But if Amazon Go is model of the future, other say that the minimum wage may become almost irrelevant anyway as automation spreads to other low-skill, low-paid jobs.

There have also been technological issues.

For example, the cameras struggle to tell the difference between similarly sized customers, so those of us with average heights and builds better be extra careful.

The technology was also stumped by kids moving items to the wrong parts of the store (aka kids being kids).

Gianna Puerini, head of Amazon Go, told the BBC that Amazon were pleased with the test:

This technology didn't exist - it was really advancing the state of the art of computer vision and machine learning.
