I have to agree. The GP is getting bent out of shape. I think him describing the limitations of the course would be useful if not worded so defensively. This is like a professional fabricator complaining that the 10 hour welding course at night-school doesn't cover welding aluminium. I don't think anyone was under the impression that this was a replacement for a an engineering degree. People will do this course because it's cool to build stuff you thought was beyond you. Also, enroll in a welding course, it's cool to be able to build big stuff out of metal too.
