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).
Fun fact, GTA Vice City is now further away (22 years) from its 2002 launch date than it was from its story setting of 1986 (16 years).
If that game were to be launched today and feature a setting in the same time delta, it would be set in 2008 when movies like The Dark Knight or the first Iron Man launched.
So when you were a child, a 1969 Mustang was a "clasic car", but now an equivalent classic car would be a fourth gen Honda Civic that your local weed dealer drives.
