Amazon plans to use automation to replace more than 600,000 workers who would otherwise be hired in the United States by 2033, according to internal documents obtained by The New York Times. By that time, the company is expected to sell about twice as many goods as it does today.

Amazon’s robotics team is reportedly working toward the goal of automating 75% of its entire business. By 2027, it is expected to eliminate around 160,000 jobs in the US, saving the company an estimated $12.6 billion — equivalent to around 30 cents per item delivered.
