Yes - fair point - we've tried that, and that's a counter-example to my generalisation. However, I'd discounted/forgotten it because the versions I've tried almost don't count as bread in my mind, as it's so seed-heavy that it doesn't have much structural integrity and falls apart very easily!
Oh I love tailscale, it is so performant and just works (mostly). However, I have used Tor for many years for this use case and still have it around as a fallback for machines that can be hard to reach spatially.
Nothing. Replacing Facebook is a perpetual tall poppy fantasy; that was the case before the privacy abuses of the last several years.
I watched the exact same thing obsess the tech world and Silicon Valley in particular, for over a decade, regarding Windows. Windows never got replaced, instead the ground changed under it, an inflection opened up new opportunities (which created nothing more than a duopoly in iOS + Android for two other giants). That's exactly what will happen with Facebook. Five or six years from now, they'll be doing a hundred billion dollars in sales, they'll be larger than ever before, and more profitable than ever before. Some day the ground will shift under them, opening up a big opportunity, and it'll require a technology shift. Then we'll probably just get another tech giant or three dominating the new thing, rinse and repeat. This is all extraordinarily predictable. The easiest thing of all to predict? Decentralization will perpetually continue to fail as a mass-consumer premise. Decentralization is the ultimate tech fantasy, and the greatest demonstration that engineers very often have a poor understanding of typical consumers. Nothing has had more thought & effort put into it, with fewer results to show for it, than decentralization for mass consumer products/services, over the last 15-20 years.
ZFS is not really a 128 bit filesystem, it is merely a 64 bit filesystem that is "128 bit ready". I.e. the on disk format is 128 bit, the kernel drivers are not. At least, they were not until Oracle bought Sun, that's about the last time I really cared about ZFS.
