I’ve been roaming Linux (meme) communities for years, but never heard of this, even though it originates from the Bell Labs. Thanks for providing me with a new rabbit hole!
It’s not like you can’t use Linux on a laptop with Nvidia GPU. It’s just that AMD works better (and isn’t as much of a PITA in how they treat regular Linux customers).
I thought I’d chuck windows on my gaming laptop an Acer nitro 5 from last year, to see how it’s going do some bits I can’t on Linux VR, certain multiplayer games etc....
I’m not sure about the easy-to-show part, but take a look at the Brightness Theorem / Conservation of en.wikipedia.org/wiki/Etendue if you want to learn more.
It’s not even coherent when the sun emits it. For one, it consists of a large range of wavelengths… And I doubt there’s a way to make light coherent at that order of magnitude.

I feel like this is a good time to point out that Linux is but the kernel. There are server-focused distros, there are consumer-focused distros. Linux supports them all; it isn’t really industrial in itself.
What OP said. But here’s a more detailed answer courtesy of GPT-4:
Adding cat /dev/random > /dev/pty23 to your .profile would result in an interesting situation whenever you start a login shell.
Behavior of the Command: The command cat /dev/random continuously reads random data from the /dev/random device file, which generates an endless stream of random bytes. Redirecting this to /dev/pty23 means it attempts to write this data to the pseudo-terminal device /dev/pty23.
Impact on Shell Startup: When you add this to your .profile, every time you start a login shell (like when you open a new terminal session), it will execute this command. Since /dev/random produces an endless stream of data, the cat command will not terminate on its own. This means your shell will be stuck executing this command, and you won’t get a prompt to enter new commands.
Interactive Shell Issue: The shell remains technically interactive, but because the cat command doesn’t complete, you won’t get a chance to interact with it. The shell is effectively blocked by the cat command continuously running.
Potential Problems: There’s a possibility that /dev/pty23 might not exist on your system, or you might not have the permission to write to it. In such cases, the command would fail, but it would still block the shell if it doesn’t exit properly.
Fixing the Issue: To regain control of your shell, you might need to edit your .profile from a different context where it doesn’t get executed, like using a non-login shell or booting into a recovery mode.
In summary, it’s a kind of a “prank” command that can render your login shell unusable until you remove it from your .profile. It’s an example of how powerful shell startup scripts can be, and also a reminder to be cautious about what gets added to them!
