ii design and build robots , they are both dangerous and productive when used correctly . amateurs have no business operating them , or working around them . it takes only one person to run the devices i build , and for every robot that goes into service , it takes at least one person to operate it . the great difference between what this man is saying and the actual reality is.... it take skill to weld , it takes years of training to run a manual mill , and a manual lathe is not simply dangerous , it is frightening to stand close to . a robot is either extremely wonderful , or as stupid as a stone , with very little difference in between . but practically speaking... it requires no training what so ever to operate , the operator must understand the controls , not what is being done ... a cnc mill is brainless in simplicity , and takes a skilled machinist to SET IT UP ... but not to run it . a cnc lathe can do in a day what it took a skilled machinist weeks or months to do , and in many machine shops , the computer numerically controlled devices do things that were not possible only 30 years ago . the machine operators of today are worth more per hour , and have a great deal less skill and are placed in harms way a good deal less often as a direct result of the machine technology... THAT IS NOT ROBOTIC .... and what robotic technology will do is employ even less skilled worker , and with less natural ability , for higher wages ... because they are worth more per hour , making more parts per hour . Marx was a profoundly stupid person with no concept of actual shop floor reality , and this man has even less understanding of manufacturing , and robotics . it is comical to the point of laughable that robotics will cause unemployment . in reality , robotics will employ the unemployed .... no business owner wants to hire the unemployed , they all want to hire people who are all ready working , or they want to do everything them selves... so that they know it was done the way they wanted a thing done ... with robotics , they get the job done the way they want it done ( by the robot ) ... but they need some one who can notice something out of ordinary , unique situations the robot was not programmed to address .... robots are very good , but they are not very smart ... for every robot you put in service , you need a person to watch over it ... the person does not have to be skilled to push a red button ... its not their job to fix the problem , its their job to respond to anything out of the ordinary . a PhD needs to work in manufacturing , before they speak on the subject ... the owners of machine shops want only one thing of the people they hire ..." do what i tell you " ... with a robot , that is what they get . they can hire even a Marxist moron to watch a robot , but getting some one to actually show up , and watch is now the only issue for the unemployed .
