I always think of automated assembly when I hear people complaining that technology is going to "replace workers and take jobs." In my opinion, most new technologies create jobs!
And yes, they may do away with some job titles but not the workers. For example, in an automated manufacturing process people watch, operate, and maintain the machines instead of producing the good themselves. But people are still needed!
Another good example of a recent automated technology where people are still needed is the self check out at the grocery store. Even though the customers ring themselves up, employees are needed to be on hand in case there is a problem with the machines. I doubt anyone lost their job because of the self check out!
