In the real world, defaults and simple-to-use libraries (i.e. not twisted) matter. Just because you are doing system programming doesn't mean you necessarily have the time/skill to carefully optimize everything.

System's programming isn't just writing a KV store used by millions. Sometimes it's writing a dedicated calculation server used in a single company. Carefully optimizing your I/O model might take longer than doing the project itself.

There is no default in C, beyond stdio. The C specification makes no reference to any I/O beyond stdio.

The author was being unfair to C. Use epoll or, better yet, libuv. libuv is a simple-to-use library.
