> The easiest case to say the simple is not enough is with encryption. I am not aware of any simple encryption algorithm. I disagree very much. Most crypto is very simple to use as well as implement. From DES to Chacha20, you can fit an implementation on a business card or two. > Numerical stability in all sorts of applications is important and it is hard to achieve. Counterpoint: I hardly ever need to worry about numerical stability, and most of the time I can just throw more bits at it. > You didn't contest my simple vs fast claim, but a good example of that is pathfinding algorithms. Dijkstra's algorithm is simple (relatively), but for many video games, a more advanced algorithm like hierarchical A* search or jump point search is needed. I wish the problem of complex software were just algorithms. Because most algorithms are easy to abstract in a box with loose coupling, and even the more complex algorithms usually boil down to some dozens of lines of code. No, the millions of lines of code in big bloated applications are not made up of that.
