1. There is very low demand for the old school "CAD guy" anymore. Schools all across the country are ditching their CAD programs, or they are renovating them into something more application-specific, which is where the jobs truly lie. These days getting an actual degree in "computer aided drawing" is like getting a degree in Microsoft Office...it's not a job in itself, rather it's a tool used to complete another job. Could be machining, welding, graphics work, electronics, mech-eng, HVAC, robotics, whatever. Yeah there are still companies that need people to sit around and make prints all day long, which is what many school's CAD programs are for, but those days are by and large gone and have been replaced by people trained in their field to use CAD on the conceptual side of things.
2. I'm not sure exactly how it is around the rest of the country, but here in michigan there is literally 1 worker per 50 jobs in the automation industry. We at the local college CANNOT fill the demand we get for trained graduates that have a well rounded background in electronics, fluid power, machining, and automation technologies. As long as the student is indeed trying to get a job upon finishing the program, they end up getting one. Even the nearby schools that have less of a budget end up placing all their students since we only have about 35 or so each year.
It just serves to solidify your point that you can become interested in a more broad application of the skills and keep "airsmithing" as a hobby. But in the process you'll be making bank on the skills used for the dayjob. You just have to find which specific application you're interested in, and make it jive with your other interestes.
