So, about a quarter of a million lines of code. Thats a lot of complexity (and hopefully power) hidden beneath the surface. Hopefully most people don't have to worry about this complexity (we try to keep the interfaces simple - try).
The thing about complexity is sometimes (just sometimes) it is necessary, and you can roll your own complexity, or use someone elses. Mostly I prefer someone elses.
For many years, sewing machines were a mystery to me. I never knew how they actually used the thread to connect stuff together.

Well not entirely relevant, but I think its cool that someone made an animated GIF showing how they actually work:
