I guess if you think flat packs and snaps and rolling releases are gonna replace the usual way Linux distributions have done things then that would be good advice for a new person.
No matter the merits of either position, I think the better advice for a new user is to learn how things are now rather than learning the rolling way.
It’s worth noting that neither way is directly analogous to how windows or macOS handle software updates because… they generally don’t! Aside from software out of either systems store, user downloaded software is now expected to run its own update when it’s launched.
Maybe that’s more like snaps because doesn’t snapd periodically run and check for stuff?
