1) This should not occur. You do not update glibc on a stable desktop environment. If you use rolling release distributions, yes shit will hit the fan (even though proponents/fans of such will deny such 'ever happening to their X years of Arch or w/e usage).
2) Don't use Nvidia; use AMD or Intel with FOSS drivers. I know this sucks if you don't have the option (its a package deal, or you already bought it).
(I've only bothered to address the first two. Doesn't mean you're correct on the other 6.)
1. Yeah it "should not" happen yet I've experienced it on a relatively sane distro. Btw "Update glibc and everything breaks" is a quote from Linus Torvalds. He's a newcomer on this scene, but he makes some good points: https://youtu.be/5PmHRSeA2c8?t=588
2. No thanks. I'll stick with my RTX 3090 for my personal desktop and 2x2080Ti for each of my servers. We both wish there was another vendor that supported tensorflow with reasonable performance, but you know that's not the world we live in.
Yeah, "Update glibc and everything breaks" is a quote by Linus Torvalds on Debconf 2014. But why? Do you know? I do. Because this very thing happened on Debian Testing. Not Debian Stable, Testing. That's akin to a rolling release like Arch. Debian GNU/Linux is a sane Linux distribution, as long as you run Stable. If you run Testing or Unstable shit is going to break, just like Arch or Nix or .. (at least Nix got good rollback support to mitigate it)
I'm happily using a Vega56 and can achieve decent performance on 1080p and 1440p on Linux. Raytracing is a gimmick to me, tear-free gaming not (but I got FreeSync working). I don't work with Tensorflow or Hashcat or such, I'm talking about Linux desktop gaming here. There's no need to use Nvidia there unless you need exotic stuff like raytracing. The AMD Radeon Navi series (5000 and 6000) deliver excellent performance.
If you are going to cite a joke, cite this: Windows, you do anything and the screen go blue. Problems exist and they need be addressed but Linux did not stop at time and the scenario is not the same as it was at 7 years ago.
