> imagine Linus has control over it and has no clue was ZFS even is

I keep getting down voted, maybe I am too annoying for HN. But I'll risk it in the hopes this is helpful, in the social and psychological space.

First of all, I have been in awe of ZFS since... ever. But FS were not my curiosity, OS was, so I installed OpenSolaris and Illumos in VMs, a few times to get used to how these things install. No work, just play. That's me. I was sad Apple did not adopt ZFS, but they did develop a read-only something, kernel extension, I think, don't recall. And there is some support from the generous for OpenZFS on OS X (idk about macOS). Why not ZFS? Because it is different and complicated, and it takes dedication to learn. Had Apple adopted it as the native FS, I would have been forced to learn it, so that is why it made me sad. I need that kind of motivation. But many are this way to some extent. Everyone is industrious and everyone is lazy. When you can learn easily, you learn. When you must learn, you learn. When you get older, you just want to keep doing things the old way, the way you know how, and you can do that for 12+ hours a day and yet learn nothing new.

Linus is just a man. I'm glad the penguinistas have faded into the background, and I am happy for Linux, but fail to see that it was any better than NetBSD when the fanatics were vocal. Linux would have benefitted from not changing a lot of userland stuff that was changed from *NIX for no rational reason, but probably just for ignorance and arrogance. Just MHO. But now Linux is important. It just is what it is.

So Linus is insanely industrious, and also lazy just like most. How often does he learn something new, how often does he just work like a mad dog without learning anything new? Just a man, perhaps a very smart man, but no more. And he is imperfect. And I strongly suspect, by the public evidence of the tell-tale symptoms, he has an identifiable personality disorder, and it is the one that includes the symptom of an unwillingness or inability to recognize the problem. But IIRC, he did admit to things, and supposedly took time off to work on himself. But this can't be cured by the patient, though it, oddly enough, can be cured, one of the few mental illness than can be cured, not just maintained, but only after getting evaluated by a professional, and treated, and the treatment is easy, just sitting with the pro and talking twice a month for 45 minutes for up to two years. At least my understanding of it, it can be cured in two years or less depending on its severity, though rarely ever is. This is not criticism, it is compassion. Presidents get this. Captains of industry get this. Winning NFL quarterbacks get this. And it is not any surprise the Lord of the Linux kernel can get this. And I wish him the best.

We're all allowed to be incorrect and imperfect. But those that stand out get better, because they try. But as far as laziness is concerned, because I am lazy, too, and I believe most are, I can't fault anyone for being lazy and not learning new stuff, especially in order to have a better understanding of it to be able to say something about it that makes sense.

However, those that do change themselves for the better, those that are not lazy and learn new things, should be applauded, and given gratitude for the possibility that their example will be followed... hopefully by me, too.
