To be precise:

1. Just because there is Linux, doesn't mean everyone should jump on the Linux bandwagon and abandon all work on illumos, NT, QNX, Fuchsia etc. Focusing everyone on Linux would kill progress.

2. Just because there is x86 or RISC-V, doesn't mean noone should invent new architectures. Apple went with their own and that's what gives them their edge now.

3. Just because there is already Emacs, doesn't mean that all editors should be Emacs mods.

4. And back to compilers, just because LLVM already has optimizers, doesn't mean that other people shouldn't explore other designs for their backends. Especially that LLVM is really slow, and a major bottleneck for new compilers now (see Rust, Zig and Jai e.g.).

> illumos, NT, QNX, Fuchsia

Who told you these are reinventing the wheel of Linux?

AFAIK, NT was a consumer desktop OS turned into server and meant to serve the foundation for both consumer and server OS.

QNX was a auto operating system, for which Linux does not work.

Fuschisa is meant to be a unibersal mobile OS.

These are not the same thing as Linux.

I did not meant to label theses as reinventing wheel. If I left you with such impression that was my fault in communication.
