Back then I used Arch because I thought it would be cool and it's what Linux wizards use. Now Arch has gotten older, I've gotten older, and now I'm using Arch again because I've become (more of a) Linux wizard.
The python (is python2) transition was even more silly though. Breaking changes to the API and they wanted (and did!) force re-pointing the command to python3? That's still actively breaking stuff today in places that are forsaken enough to have to support python2 legacy systems.
That does sound significantly longer ago then 2016 ;)
I do miss Arch but there is no way I am going to keep up with updates, I will do them when I discover I can't install anything new and then things will break because it has been so long since my last update. Slackware is far more suited to my nature but it will never be Arch.
Why do I miss the stupid unconscious bravery of those days :)
