Wayland is a modular communication protocol that specifies how a compositor interacts with its clients, as well as a replacement for X11.
Wayland does not aim to provide a commonly used compositor implementation that could be used by everyone.

This modular approach allows for different desktop environments to have their own Wayland compositor implementations that reliability produce the same or virtually the same output based on the communication specifications without the increased challenges of integrating it into existing Desktop Environments or Window Managers as it allows for more flexibility in implementation. As an analogy, it's like if several people were making the same type of sandwich in different ways, as long as the "client" (the application) gets the sandwich they asked for, the specific process doesn't matter.

In contrast, Xorg is a single, monolithic X11 implementation. Due to Xorg's dated, non-modular design, maintaining and extending it's functionality is extremely difficult. Infact, it's lack HDR support to this day is due to its inflexible architecture.

Wayland compositors combine the functionality of a display server, window manager, and compositor into a single component. This simplified architecture is one of the main design goals of Wayland compared to Xorg/X11 where the display server, compositor & window manager are separate components. This approach ultimately streamlines the rendering pipeline where applications render locally and communicate directly with the compositor, cutting out the X server entirely. Wayland's client-side rendering is more modern and cleaner than Xorg's approach.

So you wanna go from home to school. The whole distance/trip can be done on a bus or your moms car. That's a means of transportation. But, now people are creating a train and soon you will have another means of transportation that you can go to school with, by train.

That's it, Wayland is another means of transportation (newer) than the older means of transportation that existed for a long time, x11 or xorg.

The route is how can applications show stuff on a screen, what transport should they use.

Isn't he the personal assistant to Mr Burns?

it's Xorg's opponent. The challenger.

It is the Way

I have been sort of following Wayland's development for over 10 years now. I have been using Wayland for over 2 years now. I have been reading and watching various lengthy arguments online for and against it. I still don't feel like I actually know it even is, not beyond some handwavey superficialities. Definitely not to the extent and depth I could understand what X11 was and how to actually work with it, troubleshoot it when necessary and achieve something slightly unusual with it. I feel like, these days, you are either getting superficial marketing materials, ELI5 approaches that seem to be suited at best to pacify a nosy child without giving them anything to actually work with, or reference manuals full of unexplained jargon for people who already know how it works and just need to look up some details now and then...

Maybe I'm getting old. I used to like Linux because I could actually understand what was going on…

Okay, I’m not OP but a follow up question that occurs to me reading the explanations of what Wayland is, is are there any distros or spins of distros that use Wayland by default?

it is a window protocol like x11. It is like x11 but new

it's like fight club, but don't tell them i told you 😳💦

Edit: Made the Yutani joke before I realized I'd been beaten to it.
