Working as an Automation Engineer, I can confirm that there is not a 1 to 1 job replacment with automation. Tell that to the 45 people we just eliminated with one robot and several other pieces of equipment tied together. On top of that, it was cheaper to build auotmated than to build the 24 individual machines that would have been reqired for the cell.
Also tell that to the engineers, plant manager, quality personel, plant controller, janitors, operators, receptionist, etc. that were let go with the closing of another plant from a combination of automation and Mexican outsourcing.
Oh, and I've come to the conclusion that automation acutally saves jobs in this country to a certain degree. If the entire plant is shipped to Mexico or China, then all of the above listed people lose jobs. If the plant is automated, mostly operators are displaced while other retain their jobs. Engineering may even expand in this instance.
Oh, and if anyone decries that I dislike automation, I'll tell you that you're full of crap! I love the stuff....except for the long hours at times!
