UNIX

50 years after its creation, what is the operating system that most closely resembles UNIX? What would an OS that followed UNIX philosophy to the letter look like?

can we refer to unix like oses with Unix or is that a trademark? i think it's not, only the all capital one is

linux is a kernel not an OS.

Please, not this shit again

Shit? This is not shit. This is of utmost importance.
If people use the wrong terminology we will lose our ability to communicate effectively.

an OS that followed UNIX philosophy to the letter would be not UNIX. The philosophy behind this legendary OS is amazing, but the way in which it was implemented has a major fault.
The most common and relevant interpretation of the UNIX philosophy today is the saying, "Do one thing and do it well." Every program should follow this philosophy as close as reasonably possible, and these smaller programs should all come together to make up something bigger.

Therefore, it is baffling that with such a focus on minimalism, having little programs that work with each other, and being efficient, the kernel in most implementations of UNIX is a giant unauditable several-million line monolith binary. The heart of the system is the opposite of modular, the opposite of small, and the opposite of UNIX.
A microkernel architecture makes much more sense in the traditional philosophy. The kernel would be tiny, only doing the bare minimum of what it needs to do, and containing no drivers or direct functionality. That would all be handled by userland components that all interoperate with that kernel to make a functioning system. This way would also do wonders for security, as a crash or compromise in one area does not fuck over the entire system.

It is my hope that the new major microkernel operating systems achieve great things and succeed. seL4+Genode looks promising, and the developers have stated that they aim to make it a more practical system in 2019. Fuchsia, for better or for worse, is being made by Google. Bad, because Google is botnet, but good because this system will have the financial backing to make it somewhere. Lastly, Redox seems like an interesting effort, using a new language and reinventing the ideals of UNIX in other ways.
