alt Hacker NewsI feel like most articles challenging OSes have no idea what an OS is.
Sure question what the latest tool can offer and how to integrate with it... but that's just being an app, or a window manager, or a package manager, or a distribution, that's not challenging what the OS itself is and does.
If your OS doesn't change how a computer allocates resources, then you are talking about higher level, and that can be super valuable too, arguably more valuable, but ... that's a different thing.
PS: also chroot (half a century, just checked for the fun of it), jails, containers, VMs, etc limiting how the allocation can be done do exist and have been used for decades already.

As far as I am concerned an OS is really simple to define. Its the thing that manages hardware resources on a device to allow other software to run using said resources.
LLMs are not OSes and never will be, they will always need some software to first bootstrap the hardware before the software which processes the weighting can begin.
Its like we need Richard Stallman to come and argue the difference between GNU and Linux again!
Agreed. Investing in creating a whole new phone just to usher in the concepts here sounds like an expensive and slow way to do it.
> that's a different thing.
I hear what you’re saying, but we don’t have a word for that different thing. OS means the kernel. But OS also means the entire distribution - all of macOS, all of iOS, all of windows, Ubuntu, Android, etc.
Until we have a standard word for the ui “shell” that comes out of the box with the OS distribution, people - including me - are gonna call (and think of it) as the OS. Or part of the os. Or something like that.
i.e. most users think the OS is shell, not the kernel.
Having built software runnging on everything from microcontrollers to cloud servers to browsers, I also have no idea what an OS is.
In the context of a microcontroller, is it an RTOS? How is that different from something like Embassy with Rust, where hardware allocation and coordination is handled more at build time and less at runtime? In the context of a something showing up on a screen, is an OS something providing a UI framework and hardware abstraction - something like Win32 or Cocoa? What does that make Chrome?
In 2006 it felt like an answer to the question "what is an OS" was straightforward. In 2026, I'm rather confident that I don't have a single, simple answer. If there were ever a time to re-assess what we thought we knew about computing - now seems like a good time to do it.
