What the author is talking about here is the growing pains of learning how 60-year old *NIX systems work, and shells/shell scripting. Once you learn how it works, it all works fine. But it's not easy to learn. If we had a standard education track for this stuff, it would be easier. (but there would still be people who avoid the education, rush into things, then bump their shins into the coffee table, and blame the coffee table)
