Actually, I work in industrial automation. I'm a software architect and developer by training, and I run my own small company doing work for the manufacturing sector. This requires me to dive into various disciplines that are outside of my core competencies, like electronics, mechanics, hydraulics, and specific manufacturing processes, and this is one aspect of my job that I really love.
I know you were kidding with your "only person with a job"-remark, but having spent the past 16 years on production floors in industrial manufacturing plants I can say that it is true that a certain number of jobs have been replaced by automation. During this time, a certainly relevant number of jobs has also been replaced by outsourcing to other countries.
On the other hand, new jobs have been created - someone has to design, construct, develop and maintain all this new machinery; interdisciplinary engineers, architects, automation developers won't have a problem finding a job; QA has grown in importance and headcount; and maintenance staff in factories has to have a fairly high level of preparation and expertise.
Therefore I believe it is more important than ever that kids today get a solid and extensive education. What can be automated will be automated, and many other jobs will be outsourced to the "cheaper region du jour". But there are jobs that cannot be replaced any time soon.
