Obviously. And most experienced engineers know this. But a lot of us never deal with n > 10k or so. I've worked a lot in embedded, and even when n is large, it's usually just moving around a payload. Even when I've dealt with n>>10k, say writing a network server, I've rarely been concerned with complexity. I focus on doing the minimum amount of work possible. It's basically the same thing, without the academic formalism. The main rule of engineering seems to be "don't do stupid things()."

- except when it doesn't matter.
