I have used Arch for >13 years (btw) and use the terminal every single session. I also work with Linux servers daily, so I tried the other families with DEs (Debian/Ubuntu, RHEL/CentOS/AlmaLinux/Fedora).
I’m comfortable (and prefer) doing everything with CLI tools. For me, it’s a bit difficult to convert my Windows friends, as they all see me as some kind of hackerman.
What’s the landscape like nowadays, in terms of terminal requirements?
Bonus question: Which distribution is the most user-friendly while still updated packages? Does anything provide a similar experience to Arch’s amazing AUR?
The terminal lets you delete the system with the same checks as GUIs, i.e. you’d be prompted for a privilege escalation password… If you delete random user files in the terminal then you can do that in a graphical file browser too. Just don’t run random commands without knowing what they do.
