> I don’t really think that you can do everything just with data structures and relationships. No, you can't do everything with just data structures. Everyone knows this. 1st-year junior programmer knows this. It's obvious. The original question did not talk about this, you misunderstood the level of analysis it was aiming at. The fact that SQL is not turing complete is a meaningless truism here, because Linus obviously did not mean that we should all start using SQL instead of C. The point he is making is that data structures are of much bigger importance to get right in order for the program to be good. Not just fast or just maintainable, or just easy to understand. But all of those things and many others.
