I disagree. There are crafts people who do awesome woodwork, but woodworking is a hell of a lot easier to learn that software development. Also, my dad was a welder, a very good one, but most of the welders he worked with were drunk fools and did 'acceptable' enough work. If you have half a brain you can learn to weld and even fabricate metals. I've been in that world and I know exactly how smart those people all are (hint: most dropped out of high school).
