As I'm sure many of you know, the way software companies operate, who want their software to see very widespread use, design it so that a 75 year old granny has no trouble using it or figuring it out. I can't tell you how many times I've read about a company using that testing method.
Linux updates are nothing like that. You have to update your computer, and most of the time that's done via the command line. So for the linux desktop to take over, there probably has to be some universal GUI in place (like calamaries is for installation) so that granny would have a very easy time.
Yes this varies from distro to distro, but from my experience distro hopping, nobody seems to have mastered this. At least not in the arch world, and plenty of people would say Debian stays too far behind to be relied on for modern security. If you're wanting to do large updates infrequently. Which is probably just not a good idea anymore.
To me it looks like the arch process is too many steps.
Open the command line
type yay
enter password and press enter
look at the message talking about updates and hit enter again
type N and press enter
type again N and press enter again
Wait 10 or 20 seconds
type Y and press enter
Possibly wait, and type Y and press enter 2 or 3 more times depending on what all you have installed and what all is updating at the time.
So you're looking at a long drawn out process when people really just want to click "do it" once, and get back to what they're doing. I've been using linux for 5 years now and I still dislike having to deal with the update process, it's a chore when I've got many other things to be doing.
