In order to understand complexity, a good strategy is always to take something apart and try to rebuild it. This is exactly what a few volunteers, lead by a former Safari developer, set out to do. They are building SerenityOS, a full-fledged operating system, and Ladybird, a web browser, from the ground up (so: no borrowing an existing module for e.g. reading a JPEG file). Like true engineers, they are doing this for fun. That’s all well and good, but you can’t really build a serious web browser...
