Wayland was first released in 2008, so it's 15 years old. Xorg was a fork of XFree86, which was released in 1991. So that codebase was 17 years old when Wayland was first released. I don't think the date of the fork is what's relevant here. I could also argue that you should be comparing the Wayland protocol (2008) vs the X11 protocol (1987), or even older versions of X (1984).
