Also robot welders don't get the health side effects of a lifetime of welding. My first job in IT was for a place that was on the front edge of robot welding in '98. We had a couple of guys that were in their 60s that could barely breathe or see that toddled around the shop floor. I found out that those guys were the "real" welders that would tell the computer guys what they needed to change in the code to get the plasma cutter to do its cut properly, welder to do the weld correctly, etc.
