In practice, the Linux community is the wild wild west, and sweeping changes are infamously difficult to achieve consensus on, and this is by far the broadest sweeping change ever proposed for the project. Every subsystem is a private fiefdom, subject to the whims of each one of Linux’s 1,700+ maintainers, almost all of whom have a dog in this race. It’s herding cats: introducing Rust effectively is one part coding work and ninety-nine parts political work – and it’s a lot of coding work. Every subsystem has its own unique culture and its own strongly held beliefs and values.
The consequences of these factors is that Rust-for-Linux has become a burnout machine. My heart goes out to the developers who have been burned in this project. It’s not fair. Free software is about putting in the work, it’s a classical do-ocracy… until it isn’t, and people get hurt. In spite of my critiques of the project, I recognize the talent and humanity of everyone involved, and wouldn’t have wished these outcomes on them. I also have sympathy for many of the established Linux developers who didn’t exactly want this on their plate… but that’s neither here nor there for the purpose of this post, and any of those developers and their fiefdoms who went out of their way to make life difficult for the Rust developers above and beyond what was needed to ensure technical excellence are accountable for these shitty outcomes.
…
Here’s the pitch: a motivated group of talented Rust OS developers could build a Linux-compatible kernel, from scratch, very quickly, with no need to engage in LKML politics. You would be astonished by how quickly you can make meaningful gains in this kind of environment; I think if the amount of effort being put into Rust-for-Linux were applied to a new Linux-compatible OS we could have something production ready for some use-cases within a few years.
…
Having a clear, well-proven goal in mind can also help to attract the same people who want to make an impact in a way that a speculative research project might not. Freeing yourselves of the LKML political battles would probably be a big win for the ambitions of bringing Rust into kernel space. Such an effort would also be a great way to mentor a new generation of kernel hackers who are comfortable with Rust in kernel space and ready to deploy their skillset to the research projects that will build a next-generation OS like Redox. The labor pool of serious OS developers badly needs a project like this to make that happen.

Riiight… Because those developers would always be of the same opinion… Good luck with that.
When the alternative is dealing with ignorant old men too stuck in their ways to learn and grow instead throwing vitriol and outright bullshit. You bet. That video was painful to watch and frankly some heads should roll.

They will die out, just need to outlast them for progress to be made.
(Ignoring the ageist and sexist “old men” statements in this thread because it’s irrelevant)
They will die out,
… and be replaced with other technically invested people who are resistant to change. Such as with every massive project ever - at least until you get a tyrant who ignores the feelings and work of of others and is in a position to push through their own vision.
They are not being replaced at the same rate though. Knowledge brings understanding, understanding bring empathy, empathy brings change.
Bless you for being an optimist, but I don’t think it works like that. I really wish it did though.
Why else would Republicans ban books, keep their children in the dark about other religions and people. So they can keep them on the hate train.
Man, despite loving Foss this whole debacle is so disillusioning for anyone that ever wanted to pivot to working on it full time. You don’t have to agree with people wanting to try new things, but the bare minimum is not to spew vitriol to keep them quiet or claim you’ll break their stuff and that’s their problem because they aren’t doing things the same way as you but still depend on a shared ecosystem. All we have to do is be bloody polite to each other and build cool sh*t, why is that so hard. All the best to the Linux rust rewrite for these folks, but to me it just feels like both projects are losing here. Linux losing the passion and drive for adopting more modern stuff and all the folks with that drive opting to restart from scratch because too many people refuse to get along.
I wouldn’t be surprised if a Rust-based Linux fork eventually happened (possibly funded by some techbro wrecker)
Drew DeVault recently wrote a simple but functional UNIX kernel in a new systems programming language named Hare in about a month, which suggests that doing something similar in Rust would be equally feasible. One or two motivated individuals could get something up which is semi-useful (runs on a common x86 PC, has a console, a filesystem, functional if not necessarily high-performance scheduling and enough of the POSIX API to compile userspace programs for), upon which, what remained would be a lot of finishing work (device drivers, networking, and such), though not all of it necessary for all users. Doing this and keeping the goal of making it a drop-in replacement for the Linux kernel (as in, you can have both and select the one you boot into in your GRUB menu; eventually the new one will do enough well enough to replace Linux) sounds entirely feasible, and a new kernel codebase, implemented in a more structured, safer language sounds like it could deliver a good value proposition over the incumbent.
I’m not sure I’d call device drivers ‘finishing work’.
The MAJORITY of the kernel is that pesky bit of ‘finishing work’; there’s a fuckton of effort in writing drivers and support for damn near ever architecture and piece of hardware made in the last 30 years.
You could argue you don’t NEED to support that much stuff, and I’d probably agree, but let’s at least be honest that the device driver work is likely to be 90% of the work and 90% of the user complaints if something doesn’t work.
There’s a Pareto effect when it comes to them, in that you can cover a large proportion of use cases with a small amount of work, but the more special cases consume proportionately more effort. For a MVP, you could restrict support to standard USB and SATA devices, and get a device you can run headless, tethered to the network through a USB Ethernet adapter. For desktop support, you’d need to add video display support, and support for the wired/wireless networking capabilities of common chipsets would be useful. And assuming that you’re aiming only for current hardware (i.e. Intel/AMD boards and ARM/RISC-V SOCs), there are a lot of legacy drivers in Linux that you don’t need to bring along, from floppy drives to the framebuffers of old UNIX workstations. (I mean, if a hobbyist wants to get the kernel running on their vintage Sun SPARCstation, they can do so, but it won’t be a mainstream feature. A new Linux-compatible kernel can leave a lot of legacy devices behind and still be useful.)
ReactOS is probably a good indicator how far you can get with some limited generic drivers.
The ignorance being referenced is next level. Frankly some heads should roll on this, if you dont know the language shutup. You have nothing to add.
Old man yells vitreol and nonsense.

There are three similes in that quote. When your considerations are that disorganized, you have not finished thinking everything through. Fiefdoms, dogs and cats … oh my! That’s on top of wild west and other trite, well worn and rather silly similes.
Make your argument without recourse to inflammatory terminology and similes and you slighten the risk of pissing people off.
Clarity is in the eye of the beholder or as someone once said: “You do you”.
