Well, programming is a tool, right? There are clearly incorrect ways to program, but that doesn't mean there's one correct way to program - because it depends on what you're trying to make.
It's incorrect to make a bookshelf that can't hold the weight of books, but IKEA isn't incorrect to make a crappy-but-adequate bookshelf that will get given away when you move, and a master carpenter isn't incorrect to make an expensive-but-beautiful bookshelf that will be used for many decades.
A seed-stage startup trying to see if anyone cares about their product at all should probably accept it being 100x slower than it theoretically could be. And the Linux maintainers should be working hard to shave milliseconds.
