> And finally after all those years Wayland will turn into what X11 is now
I doubt that, the developers of the Wayland protocol and Weston and other window managers have a much better idea of what the state of the art of graphics looks like and are likely to be in the future vs. the original X11 developers in the 1980s. I don't expect things to ever be as complicated or fundamentally broken as the X11 protocol, we just know more about designing this kind of thing now.
> Wayland is not going to be as stable as X.Org
I call BS. It's using the same underlying graphics infrastructure as X11 is using but with less broken behavior in the middle so it should be much more stable, with less surprises, than Xorg can be. It's not going to be worse, it can only get better.
> The main question is: why spending 10 years for making Wayland as good as X11, if we already have X11 today?
You think X11 is good, which puts you at odds with the people who work directly with X11. We don't just "have" X11 today, what we have is an on-going, heroic effort to keep it working and support modern devices, which is failing.
