If you're early in your career and looking for something useful to learn, SQL's a good bet. It will probably outlast every other part of the tech stack you now use. Everything the author says about SQL is true. But, like asphalt for roads and aluminum for airplanes, it still can stand a lot of improvement. By the way, it's just as important as asphalt and aluminum, and consequently just as hard to change. That's the curse of the customer base. I wish the SQL world could agree on standards for string manipulation, and stored function / proc programming.
