Amazon will be using 10,000 robots in its warehouses by the end of the year.

Do not worry, they are helping people work, not replacing them =)
While robots are playing a growing role in fulfilling orders in the warehouse, it could still be years before Amazon sends packages via drones to customers’ homes. Bezos plans to have drones deliver packages to your door in 30 minutes, but there are a number of legal and technological hurdles before that can happen.
For now, you’ll have to visit the warehouses to see a robot helping to deliver your package. Amazon (AMZN, Fortune 500) started offering public tours this month.
