Amazon has introduced humanoid robots, such as Digit, into one of its U.S. warehouses for a trial run, aimed at enhancing operational efficiency 

Digit, developed by an Oregon-based startup, is a 5 feet 9 inches tall, 65 kg robot with the unique ability to walk on two legs, grasp, and transport various items 

Concerns have arisen regarding the potential impact of this automation on Amazon's workforce of nearly 1.5 million employees 

Amazon Robotics Chief Technologist Tye Brady emphasizes the intent to automate mundane and repetitive tasks, which will free up employees for more engaging roles. 

A workers' union expresses concerns over job losses and compares Amazon's automation efforts to treating workers as "robots." 

Amazon has launched humanoid robots, such as Digit, in a trial run to automate warehouse operations and improve efficiency. 

The future will likely involve a careful balance between automation and job preservation as companies like Amazon continue to advance their operations.
