> what's so wrong with X11 so people need to replace it
1. Security - Any program using X11 can read keystrokes, passwords, or the contents of any other window. Fixing this would break all existing X11 applications.
2. Performance - X11's client-server model doesn't work with hardware accelerated graphics, requiring hacks to get around. X11 is basically stuck with this legacy.
The ground-up re-design of X11 to fix those two issues is Wayland.
