First of all how are these MY failures and not failures of the Arch ecosystem? Running `pacman -Syu` on any given Friday should NOT leave you with a machine that no longer boots. Installing a very stable software such as fucking python3 shouldn't break litereally everything else that is linked to same lib. Everything is anecdotal, but trying to use that to dimiss literally OS breaking incidents feels silly.
If I type in `apt update && apt update -y` I can be sure that my computer will be usable after a reboot. I've once ran into an issue where the next kernel update didn't boot, so Ubuntu booted me back into the previous version and told me the issue. This is exactly the kind of thing I want my OS to protect me from. I am not a kernel developer and don't have sufficient knowledge or interest to get into that. I also don't want to be afraid to update my software.
I have nothing against Arch or its users, but I wouldn't recommend it to anyone who actually needs to use their computer and isn't willing to spend a day every now and then fixing their OS.
Just as a side note on this rant: My experience is by no means unique. The whole reason I even gave Arch a second try (after the python3 library ordeal) was that my colleagues are using Arch as their daily driver, but even with them every now and then I hear how they have to fiddle with their packages to make things work/compile or that they updated something and something broke (often it is audio).
