It can't have a longer life than something that's repairable and upgradable.
Even if we imagine Apple used the highest quality components, which they most certainly didn't, anything dying means you need to completely replace the internals of your device. It's like saying a car that needs an engine replacement because of a dead spark plug can have a long life.
For my wm+Emacs work, I unified the shortcuts by calling a separate go bin that checks if the active window is Emacs or not. If it is, it sends the command to the Emacs Daemon. If it's not it sends the command to i3. For directional commands like move focus, first check it there's an Emacs window to that side, if not send the command to i3.
They have frequent releases that introduce features and bugs, and then they squash them every week.
A stable distro like Debian will only update KDE once every ~2 years. If the version they use is full of bugs, you're stuck with it.
On the other hand you've got a DE like xfce that gets a release every few years, and the Devs make sure it's as reliable as possible to fit that stable release schedule.
