You left your cousin with arch installed but didn't tell him that it's necessary to keep a rolling release distro up to date?

Hell, I have to keep up with the mailing list and the news page on the website just to keep my OS working update to update.

It's worth it for me because of my needs but Arch is very very specifically NOT for the average user.

You basically set your cousin up to fail. And it's not like the branding and messaging isn't clear about any of these things. Why on earth did you pick Arch for this use case?
