Amazon's new artificial intelligence included a secret ingredient: about 1,000 Indian employees - voila! news. The trading corporation's "Just Walk Out" technology was supposed to be the next step in the world of retail - which is based on computer evidence.

But then it turned out that the intelligence is not really artificial and the evidence is not very computerized. Now on Amazon - removing the technology from the stores and replacing it with smart carts - where customers can remain independent and avoid standing in line at the checkout.
