Well known KDE developer Nate Graham is out with a blog post today outlining his latest Wayland thoughts, how X11 is a bad platform, and the recent topic of “Wayland breaking everything” isn’t really accurate.
“In this context, “breaking everything” is another perhaps less accurate way of saying “not everything is fully ported yet”. This porting is necessary because Wayland is designed to target a future that doesn’t include 100% drop-in compatibility with everything we did in the past, because it turns out that a lot of those things don’t make sense anymore. For the ones that do, a compatibility layer (XWayland) is already provided, and anything needing deeper system integration generally has a path forward (Portals and Wayland protocols and PipeWire) or is being actively worked on. It’s all happening!”
We’re getting well away from the topic now. It depends on what you mean by “replace”. Railways and canals exist side-by-side as different solutions to similar problems - sure. And some railways have replaced some canals. But the panama canal will not be replaced by a railroad for example. It couldn’t do the same job. The pros/cons of each option depends on many factors.
The analogy is poor for comparing software. Linux distros will likely replace X11 with Wayland over time. To do the same thing that X11 was doing. It will be replaced “in place”. The very same thing you were using with X11 will now need to work on Wayland. This would be like running your barges on the railroad? Maybe? Depending on how you squint?
I wouldn’t expect my barge to work on the railroad. I do expect that Firefox will run on Wayland after having used it on X11 for 20 years.
But as a user of a barge if you needed wanted to use railways. Because they are faster. It would be the barge maker or a new train maker you would look at. Not the railway.
Just like canals X11 still exists. And is still being developed. It has its limitations but some applications are choosing not to port. Because like barge makers. They simply do not see the need. Or merit.
If the makers of railways insisted that all current users agents had to work on them without adaption. Many of the advantages would no longer be there.
Just as if waylaid did not expect Firefox et al to adapt to its methods. The security and other advantages they seek would not be practice.
Waylaid is a replacement. Not an upgrade.
(PS yeah living in the UK replace canal with inland waterways navigation. Tends to be how we think of it. As they are such a huge part of our industrial history. I forget the US really never went through that part of europeen industrial development. Your example is a fairly unique and modern by comparison, it dose not link to any network. Where as the inland waterways accross the UK and parts of Europe were a linked inferstructure like our railways. When the railways in Europe were built. They were very much seen as a replacement to our existing canal system. By both the corperations set up to build the inferstructure and the media of the time. It is literally a part of our industrial history thought is schools here. As so much of our culture and industrial revolution is built around the events)
